I'll second what Tony says, especially if you use the omni antenna's he
has designed (which I also use and highly recommend - and they're really
easy to build).
While Tony is modest, you can get his design and construction details
for both his 146 and 435 MHz antenna's in the 2006 AMSAT Symposium
Proceedings (available on the AMSAT website - I know a callous plug!!).
What? No AMSAT Proceedings handy?? Then try the current August 2007
issue of QST where Tony describes his 2 Meter EZ-Lindenblad. (Tony -
will the 70cm antenna be in next month's QST??)
