Im going to make this j pole http://www.packetradio.com/JPOL4EVER.html
in the calculator for the dimensions i would put 27 mhz for the freq right?
Isn't 26 ft a little much?
thanks

Why not put the exact frequency in there (say 27.205 MHz for Channel 20)?
The length looks correct for 11 meters. Remember frequency and wavelength are inversely proportional: the higher the frequency the shorter the wavelength (and therefore the shorter the antenna for a given type).

Thanks a lot for those links, but now im more interested in building something a little smaller like a 1/4 wave ground plane but im looking for more detailed plans- and would steel conduit work?
Thanks again
Thanks again
that seems like it would be real heavy. look around for old antennas in your area and get all you can and make and antenna out of the pieces. you might even get lucky and get a working antenna.
When you say "quarter-wave ground plane", you've described the antenna in enough detail so as not to NEED any detailed construction plans.
