radio trouble

Recommended Posts

I just installed a new Icom A200 radio in my veze and am having a problem with transmitting any distance. I originally had a portable icom with a remote antenna behind the pilot seat in a vertical position and it worked ok but still would only transmit aprox 25 mi. so with the new radio I installed an antenna on the bow leg but it won't even reach out 10 mi. any sugestions on how to get more range. In my earlier yrs. we would attach linears to our CB radios to reach out and touch someone. is there such a thing for vhf radios. thanks the Rebel

most likely the antenna. find someone with a signal strength meter and test the antenna. is that 10 miles in the air or on the ground? remember the signal is line of sight.

A couple recommendations

 

1) The Comm antenna should be as vertical as you can get it. Although a horizontal antenna will work, your signal will be approximately -20db (about 1/10) down from an identical antenna that is vertically polarized.

 

Aviation Comm is vertically polarized, VOR Nav is horizontally polarized. These selections were made to specifically take advantage of the 20db isolation between Vert and Horiz

 

2) Find a ham operator and see if they will put their VHF VSWR meter on the antenna. (a CB VSWR meter may not work, different frequencies). you need to see about 1.2 to 1.5 across the entire VHF range. (less than 2.0 is acceptable).
