Hi Howard. Congrads on the R5, as it is A great antena. I wish I had never gotten rid of mine. It does not need radials and the coax length is not criticle as it feeds a 50 ohm load. I never made any adjustments to mine, just set it according to the directions, and put tape on each section to mark the spot, when I took it apart. Ibought it when I still lived in Michigan, took it apart and moved out here to Arizona, and took it apart again when I moved to my own qth, after I was here a month and it worked fine. The thing I like best about that antena is that it actually exibits some gain on 10 meters, unlike many multi-band virticals, that trap off most of the antena on ten, so you are using the bottom eight feet or so. There are no traps in the R5. HTH: John ________________________________________________________________ Sign Up for Juno Platinum Internet Access Today Only $9.95 per month! Visit www.juno.com
