I'm building an RV7A with one SL-30 radio and inside the wingtip antennae.

I'll probably use the Sport Aircraft design for the antennae.  Question is,

can I use a diplexer "backwards" to feed the one VOR with two antenna feeds

to both boost signal and reduce shadowing effects?  Would a standard

diplexer work, or would I need something special?



Thanks in advance,



Terry

You are talking about diversity reception. Google that term and lot's of things pop up.

I use it a great deal with wireless mics. Go to this website for starters...

The problem is, the antennas can not be tied together as the signal one picks up will not

be in phase with the other antenna. The result is a reduced signal and in some cases complete

cancel of the signal. 



So how do the dual antenna receivers do it? They constantly sample the antennas and 

*switch* to the antenna with the most signal.
