How to Setup Your GPS Antenna?

A 4G carrier network usually provides only high-speed Internet. In your modem or mobile phone’s product packaging or box it might indicate there to be “4G”, but don’t get that wrong there. It only goes to show that the device is capable of establishing a connection to the Internet through 4G enabled areas.

You can verify this from your carrier’s coverage map. By this measure, you’d know if you can operate within their offered 4G covered zone, just before you decide to go any further.

If you happen to be situated in a rural to a suburban area or you happen to be traveling, there is no need for you to have access to a 4G antenna.

So, what kind of antenna to look for?

The 700MHz or Band 28) and the 2600MHz, also known as Band 7. These are two new frequencies that you can take into consideration.

700 MHz is a qualified wide span network, a long-range one. If there should be one drawback here, it should be that its base station can only accommodate a limited number or same amount of subscribers, but currently can cover a much larger geographic area.

This signifies that the 700Mhz is going to be a lower speed network and this can be attributed to the increased number of users. Therefore to reach the best possible speed, a little trick may be necessary to get on the way.

Multiband antennas

While the configuration of the network is set first at 2600 band preference and 700 MHz as the last, higher performance can be made possible with the use of an antenna the comes with a much higher gain in the upper bands. This allows the modem to achieve a connection, an association to such networks to provide higher connection capacity.

To make use of such network features to our advantage, we need to look at how the majority of available antennas operate or work across multiple bands, normally by LPDA or high-performance panel.

Multiband antennas have their share of the dark side, and that is when it comes to increasing the operating bandwidth, you need to lower antenna gain. Another option is to come with a heavy and large antenna.

To maintain the level of practicality, multiband antennas need to sustain a maximum gain of around 10-11dBi.

High Gain Antennas

It is possible to establish a long-range 4G connection, and this is made possible with the use of high gain antennas. High gain antennas come available at a frequency bandwidth cost, meaning to say at ranges that come more than 20km, you need to pick one frequency to continue operating.

Since not every single 4G base station is capable of broadcasting all 4G frequencies, it is of prime importance to make some research first to figure out the frequency that the target base station is operating on before the selection of an antenna.

How to Know If You Are Using the Right VHF Antennas?

It is easy to fall in love with a new multi-function display when trying to look for a good buy on marine electronics such as those that come with features such as the VHF/AIS combo. But things will take a different turn when you need to look for antennas and transducers.

If things are alright, including the radio model and the antenna height, there is no way that you can’t go from 10 miles to 25-plus miles ranges just based on the materials being used in manufacturing the antenna.

Hence, expert minds in the industry recommend that you not settle for anything less than the best antenna that your money can afford. The price range for this could go from $30 up to around $300 or so, and this would be for the majority of recreational fishing vessels.

Defining Marine VHF Antenna

Some of the leading brands of marine VHF antennas would be grouping their product offerings into 3 basic categories. These would be correlating to good, better, and the best of their product offerings.

The key differences they would usually have will range from a combination of coax, what is inside them, whether coaxial cable, brass, and copper. Sometimes it would also come in all brand copper, which creates the greatest efficiency which almost everyone else is what is looking for.

Before we dive into dissecting antennas, it is of paramount importance that anglers have a good level of understanding of what an antenna is, and what it is all about. It is a machine, although the first impression that many people initially have about it is that it is just a piece of wire.

These things that we build are physically resonant circuits, catered to the frequencies that we are aiming to utilize. The primary function of an antenna is to convert electrical signals and transform them into photons. Therefore, we can safely say that they are photon generating machines.

In addition to that, consumers are usually under the notion that VHF antennas would be transmitting its signals only from its tip. However, we want to take this opportunity to correct this now and make an affirmation that antennas are actually radiating their signals from the base up.

Due to the surrounding energy in an antenna and the fact that signals travel only by line of sight, where you intend to install it aboard a vessel is crucial to how efficiently it will work. Even the best or the leading brand of antennas will not work well when you have placed in very close proximity to another antenna that is also utilizing the exact same frequency it is using (another VHF or AIS). This also happens when you mount your antenna too near metal objects, or if they are too low.

Durable Marine Antennas (VHF Type)

Most of the time, an angler would have broken his VHF antenna even before it dies out on him for natural causes. The lifespan of an antenna is hard to establish these days.

Some can last for up to 2 years only while some can last much longer than that, for up to 30 years. This will have to depend on how much you are taking care of it, and what grade of antenna you acquired.

Higher quality antennas sometimes come with UV blockers, and the paint they come in makes it all possible for them to ward it off. There are instances also that they would come instead with heavy-duty fiberglass. Another is that some models would come to the market in stainless steel as opposed to having plastic mounts.

If you are a seasoned boater, we recommend that you wash your VHF antenna with water and soap whenever you need to. The use of abrasive detergents can be harsh to the fiberglass and thus are likely to strip the surface finish off. There is nothing to worry about in applying wax because they are not known to make any kind of interference to the antenna function.

The Best UHF Antenna Frequencies for Your Wireless Microphone System

A wireless microphone system receives and transmits on a radio frequency or also known as operating frequency. The allocation and regulation of frequencies and bands vary from country to country. Aside from frequency that present in a UHF antenna, government agencies also specify other aspects of the equipment. This includes maximum deviation, allowable transmitter power, and spurious emissions among others. All these specifications vary from one band to the next and from one user to another.

VHF and UHF Antenna for your System

UHF and VHF regions has various bands that are utilized for various systems. But there are some regulatory, physical, and economic disparities between these two that needs to be noted. The main physical attributes of a UHF radio wave is the shorter length of antenna for a UHF wireless microphone system.

One consequence is lesser radio wave transmission both through air and non-metallic materials like human bodies and walls. As a result, there is less transmitting reach for radiated power. One more consequence is the higher amount of radio wave reflection by smaller-sized metal objects which results in more severe and frequent duo to multi-path.

Knowing the Regulations

The regulations for both users and for licensing are the same in the UHF and VHF bands, regulations for the material would allow two possible differences. In the case of FM signals in the UHF band, greater bandwidth is possible. This allows greater deviation for wider frequency scope, as well as wider dynamic range of audio signal.

Additionally, a transmitter power up to 250mv is possible. Lastly, the available radio spectrum for UHF wireless microphone system usage is eight times higher than those with a VHF. With this, there is a larger number for a wireless microphone system to be operated.

The effective higher deviation limits of a UHF are not used as this results in the reduction in the number of systems that is operated: the corresponding enhanced occupied bandwidth of every system utilizes more than the available frequency reach. At the same time, the use of improved transmitter power is not common as this results in a decreased battery life and mutual interference.

But for UHF systems that has less than the maximum limit of power and deviation, the capability of a higher number of simultaneous systems is an important benefit in specific applications. This is true since a UHF system could be used along with a VHF system.

The main economic difference of a UHF and VHF operation is that UHF equipment has higher cost. Usually, it is a lot more difficult and expensive to design and make UHF devices. This is the result of the behavior of short wavelength/high frequency radio signals. The current UHF system cost more than a VHF system. Such cost differential is applicable to cables, antennas, and other accessories and the basic receiver and transmitter.It is very evident that the use of UHF antenna has greatly change our lives today. If you want to upgrade your wireless microphone system, be sure that you opt for the best quality one. Click right here to know the other benefits of using a UHF or VHF antenna.

How to Install a GPS Antenna System for Your Car?

In the first place, what exactly is a GPS antenna? How does it work? GPS with antenna, these are modern tech devices that receive and amplify radio signals that are being transmitted by GPS satellites on specific frequencies. They are then converted and become an electronic signal to be used by a GPS receiver, which allows the device to make a precise computation of its location. 

When you install an in-dash navigation receiver, it is somehow comparable to the installation of regular touch screen stereos, well at least for the most of it. But know that there are a handful of setbacks here, the reverse direction sensor and the antenna. 

Proper Installation of GPS Antennas 

When it comes to installing external GPS antennas equipped with in-dash navigation receivers, there are simple guiding rules you need to keep in mind. The first one here never attempt to modify the antenna in any way. 

Even making cuts to it can lead to serious repercussions. Another thing to remember, you need to ensure it is always in perpetual contact with various GPS satellites that are in orbit to the earth. The best way to ensure this is to mount it in a position that will have minimal interference with its signal.  

How Obstructions Affect Your GPS Reception

GPS navigation systems will only carry out their expected functions when they can receive needed signals coming from a web of global satellites that comprises the Global Positioning System. 

By taking into account directions that is being indicated by multiple satellites, the GPS machine can make calculations of its physical geographic location. The margin of error here is very much alleviated. 

One of the requisites for a GPS device to work optimally is a clear sky, completely void of any obstruction. Otherwise, it will have difficulty in grasping satellite signals. This happening can pave the way for it not to operate, or it will still function but with a much-degraded accuracy. 

When GPS for car’s level of accuracy deteriorates, it can be due to surrounding structures such as surrounding tall buildings, or skyscrapers that are yonder your location or any other similar infrastructures. However, it must be remembered that car roofing systems can also serve as an obstruction to the strength of the GPS signal.

Best GPS antennas

If surrounding obstructions are inevitable, there is one effective way to mitigate its effects and that can be done by placing your GPS antenna locator by your car window. But then again, there is a possibility that doing this in your own car may present you with some unique challenges as opposed to vehicles.

And there is no other way to determine this other than giving it a try. For example, metal roofs have a natural tendency to produce an even more intense RF shield when compared to ragtops. If your vehicle happens to have tinted windows, chances are high that they have tiny metal particles in them which can also cause some disruption to your GPS signal’s strength.  

If the GPS with antenna  you have fails on you when it is trying to obtain a signal, or if there are many observable occasions that it is giving you inaccurate and obviously unreliable data, then acquiring an external antenna is highly recommended. Usually, this measure will significantly help in fixing the problem.
