Hi Randy
I've had a lot of luck in building the designs from this site.: http://dk7zb.fox28.de
The designs are very simple to build and produces a good gain and pattern. Above that there's a lot of yagis for both the 2m and the 70cm bands, there are some 50MHz, 70MHz (4m band in europe) designs and some designs for the low bands as well. On the site is also some instructions on how to make the single polarized yagis into circular polarisation.
Hope you can use this for something :)
Regards Martin, OZ1TMM

I have been wanting to put up long boom oscar antennas for 2 meter and 435 bands but the prices are very high. Are there any websites out there with plans that show how to build a cross polorized antenna for these two bands. I'm sure one could be built for half the price of the M2 satellite antennas. Also i have search the internet for plans that show how to build the circular polorization switch for LHCP/RHCP but have yet to find one. Any help will be greatly appreciated. _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
