My KR2 is somewhat complete, and did not have provision for radios due to the previous owner only needing a handheld to accomplish his mission. I am attempting to follow RST's recommendation on the location and design of the com antenna, following Mark's example, and install it in the rudder. Can I install it on the surface of the completed rudder >Colin Rainey +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Check out www.advancedaircraft.com They have a 1/2 wave dipole that I have found to work GREAT. I'm using an older model Sporty's hand held, mounted on a swing down, hideaway mount that allows the radio to be moved up and out of the way for entry and exit and then swings down between my knees for flight. I use a quick disconnect for aircraft power, run it through a two place intercom, and use the AAE antenna. My little $150 used Sporty's sounds just like a $1200 panel mount to the people I communicate with. You can get intercoms that are hardwired with the plug that plugs right into the handheld so you don't have to do any wiring there. I can remove the radio in about 15 seconds if I care to use it as a handheld. My antenna is located in the tailcone with the center coax connector block tye-wraped to a 5/8" cross member. The ends of the antenna curve forward where they meet the fuselage floor and the turtledeck. Setting in my workshop I'm able to pick up the AWOS and VOR at an airport five miles away with a strong enough signal to give me a VOR bearing. I can pick up the ATIS at another airport eight miles away in the other direction. I've talked with a friend of mine in his Acro Sport II when he was flying about 20 mile from my work shop and regularly monitor airline traffic for who knows how far out. Also, with the AAE you don't have to worry about a ground plane, etc., just strap it in and go. They seem a bit expensive but THEY DO WORK. I'm not sure of the design so I don't know if you could build one yourself or not. Perhaps someone on the net could tell us. The elements and connecting block appear to be potted in resin with the element portion very flexable. Larry Flesner
