- Your 2-way radio antenna is weather check, missing the top cap, some outside sheathing or has a crinkle or big bend in it. Exposing the coiled wires within to outside elements can oxide or corrode the metal, causing them to be inefficient and reduce range. If you can bend the antenna and see the metal coils or it is crooked in appearance like someone shut it in your car door, you need a new antenna.
- You are not using the correct antenna. Somewhere along the line you decide to use another antenna on your radio. It seemed to fit, so you weren’t worried, despite being shorter, taller, VHF vs. UHF, etc. See #4 below.
- You’ve used the antenna as a handle. This can strip the threads, or pull the antenna connection loose from the component board. When this happens you will need to get your radio into the repair center, or in some instances there is a chance the radio would be deemed non-repairable due to non-reversible damage to the component board.
- Any of the above three problems can also lead to a radio problem called reflected power. Instead of doing its job of getting all the power away from the radio and returning none to the transmitter, the bad antenna reflects the power back down into the radio and beats up the transmitter. This can quickly lead to a radio needing repair.
A good rule of thumb to remember is HEIGHT and PLACEMENT determines range. Holding your radio upright, perpendicular to the ground, will give you the best range. Tilting your radio to the side or using a stubby antenna will reduce your range by up to 2/3s. Educate your radio users on how to hold their radio for best range, you will be amazed at the difference it makes.
