Your best option for mapping and navigation no matter where you go in Australia. Back Moderator. This is great for hills as it give you the height and depth required for communication at different levels of elevation. This is best used for terrain that is flat. The signal is more of a flat platter shape — it is long in distance but shallow in depth. Amazing for adventures in the vast outback as it goes for long ranges. Your climate and the conditions you are traveling through can also affect the signal of your transmissions.

If there is a lot of dust, cloud or electricity in the air it can cause interference as the signal tries to pass through it. Your choice really comes down to what you need it for. You should ask yourself these questions to assist in deciding what is going to be the best option for your needs.

Moderate gain antenna — Great all rounder for a combination of hilly and flat terrain. Around dB. Otherwise you can opt for both a low gain and high gain antenna to accommodate any terrain and ensure you have the required range you need.

This brings us to our next point. If you are in a convoy or a group where you are only going to be communicating with vehicles roughly 1km in front or behind you a short rubberised antenna, around mm should suffice. It is recommended to ensure at least one or two people in your group have a set up that can reach further distances in case of an emergency. If you are looking to communicate with those further than 1km radius you are more than likely going to want to invest in a fiberglass or aluminum antenna as they are a little sturdier than a rubberised one.

The length you need could be as little as 1m to one that is over 2m. This really depends on the gain your antenna provides as well as what is functional for you. This is probably the best option if you know you are going to be exploring the outback to the hills and god only knows where else!

There are a few options when installing a system with two antennas. This is most definitely a more complicated option to install. It is advised that you avoid it unless you like a fiddly-diddly-do situation. This requires your two coax cables to be the exact same length and I mean exact, otherwise you are going to end up with interference.

You also need to make sure they are a sufficient distance apart otherwise they will interfere with each others signals preventing you from getting the full advantage of them both.

This set up can just be a nightmare. This is functional and useful — however it can be a nuisance as you have two independent set ups. You must be careful with the distance between the antennas, otherwise they will interfere with each other and render them pretty much pointless! Not to mention the extra time of assembling and securing your setups. This is probably the most functional and effective of setups.

You install a switch in the cab which allows you to switch between antennas. It is also quick and easy access to both of your options whenever you require them and it is rather easy to install it. With this set up you can run more than 2 antennas if you really want — however if you make the right decision when purchasing you will only need 2 to cover all your requirements. A ground independent antenna can be extremely useful especially when mounting on a bull bar, uneven surface or even on one side of your vehicle.

Ground independent means that it simulates a ground plane to ensures it performs correctly even if there is minimal to no ground plane. A ground plane is the surface your antenna is affixed to. An independent ground antenna can also help to correct the signal range of your antenna. If you fix your antenna to one side of your vehicle it can create a lop sided signal.

Cutting and joining UHF coaxial aerial cable. I want to change the location of my UHF aerial whichis low down on my ARB bulbar, to a bolt on aerial bracket on the top rail of my bar.

However the aerial cable is permanently attached to the aerial and I can't face the thought of feeding all the way back through the firewall and engine compartment and guard to relocate it and then all the way back again afterwards. Is there any easy way to cut and rejoin it without introducing significant signal loss through the join?
