Hi Howard, Lucky you :)
Here is my personal opinion from 20 years of operations--if you cannot change polarity, don't use circular. Linear works wonderfully. M2 yagis work great no matter what polarity the bird is in...I have installed mine vertically on a metal boom. No regrets. And they are quite a bit cheaper!! My last setup purchase included three M2 yagis, and I love 'em! http://www.m2inc.com/products/uhf/70cm/44018.html http://www.m2inc.com/products/vhf/2m/2m7.html http://www.m2inc.com/products/uhf/23cm/23cm35ez.html Price those, and then compare the price to circular ones with polarity switching on the 2M AND 70cm, and you'll see one reason I went that route :) Other reasons include quality, balance on the rotors, gain, length (around 10'), durability, and simplicity, etc. Add a 2' dish on a 8' to 10' horizontal metal boom and you're good for four bands, and the standard Yaesu G5500 will do just fine with the whole mess. Don't get me wrong---circular is more of the ideal, but it gets a bit more complicated with polarity switching (not easily done remotely for example!), not to mention the expense. 73, Mark N8MH On Tue, Feb 22, 2011 at 10:06 AM, Howard Kowall <hkow...@shaw.ca> wrote: > Good morning to all > Well my wife gave me the ok to get some new base satellite antennas. > I could really only find 2 manufactures of theses antennas in North America > M2 and GulfAlpha.Is there any others,and also can anyone recommend something > I would like to be able to use them for the FM sats and Transponders. > I would imagine that circular polarized would be the way to go(rhcp) > Any input would be much appreciated > Thanks to all who read and reply > Howard > VE4ISP > > _______________________________________________ > Sent via AMSAT-BB@amsat.org.
