REFLECTOR: Poor Comm Performance

[Chuck Jensen]

Check that your squelch, sidetone, et al are set properly.  That can
fool you into thinking he radios aren't working correctly.

Subject: REFLECTOR: Poor Comm Performance



Hi all,

Since I purchased my Velocity, I've noticed very poor COM performance on
both COMs. Range is not much more than 3 miles with COM1 and COM2
appears not to work at all. Because of this, I will not fly into Class
A, B, C, or D airspace. This limits my travel options quite a bit and I
was looking for advice on new antenna placement. 

Since I'm assuming that my radio cable has disconnected from COM2 and
I'm already using an external antenna for COM1, I've looked at several
internal and external antenna options, but consistently note that ground
plane is needed for the correct functioning of the external antenna. I
can't find a single flat place that is 42" or greater and attribute the
poor performance of COM1 to this fact. I also don't like the idea of an
external antenna from an aesthetic point of view and would like the
aircraft to be as "clean" as possible.

Recently, I came across Advance Aircraft Electronics
(http://www.advancedaircraft.com/index.htm) and their linear antennas.
It seems like these would work great in the winglets. However, since I
did not build my aircraft and the winglets are already "glassed," would
this be a good candidate area for installation? If so, can anyone
estimate the amount of work this might entail (no repairman certificate
= lots of $$$)? Is there a better location for installation?

I haven't used my Terra stack in IMC, but intend to get my instrument
rating in the next year. The poor COM performance has me worried that my
antenna installations will not be up to the task. I would definitely
appreciate guidance.

Thank you
