REFLECTOR: ELT

[Laurence Coen]

Al,

243 MHz is 2x121.5 MHz.  A 1/4 wave antenna for 121.5 will act as a 1/2 wave 
antenna at 243 and thus, will be in tune for both.

  Hi AL

  My Velocity wings have an com antenna molded in each winglet .We used the 
spare antenna and mounted the ELT under the right front seat.With my ELT it 
is possible plug in a  mic and transmit on 121.5.If you do not have a spare 
antenna you might use what is called a splitter.

  That's an interesting idea.  I have one com connected to each antenna, and 
a splitter would degrade the signal strength a bit.  But I have two unused 
VOR antennas; one that I installed in the top of the fuselage, and one in 
the wing. (I have one VOR using an antenna in the other wing.) The VOR 
frequency range, 108 to 118, is a bit low, but I wonder how that would work 
for the ELT.  Probably neither the VOR or com antenna would be very 
effective for the 243 kHz frequency.
