ATC reports the #2 com in my ES is weak (compared to #1) even after
having it checked out by the manufacturer. Number 1 uses RSG/400 (or is
it RGS/400?) while the number 2 uses the old RG/58 for the ant lead in.
Could this be the problem? The RG/58 is accessible except for the last 2
ft. near the ant in the vert stab. Can I leave the 2 ft of RG/58 and
replace the remainder with the 400? Will the transition from one to the
other create a reflection problem due to differing impedances? Or should
I just leave it alone and put up with it?
Leon,
Your description implies that you have two comm antennae. What is the
orientation and composition of each? Can you switch which radio goes
to which antenna? If so, doe the problem follow the antenna or the
radio?
BTW I have some mixed RG58 and 400 in antenna lines to an antenna switch
and then RG 58 back to the tail. The only problem has been the leaky RG
58.
