[amsat-bb] Cheap Yagi Antennas for VHF/UHF: experiences?

[Achim Vollhardt <avollhar@xxxxxxxxxxxxxxx>]

Hi all,

I want to construct a UHF cross yagi for 70cm AO-40 ops. the Yagis on
the website of Kent Britain, WA5JIB

http://www.clarc.org/Articles/uhf.htm

are quoted with something around 12dbi for the 435 MHz Amsat Versions.
Has anyone experience with this antennas? particulary the quite 'flat'
and unconventional driven element seems funny to me.. I have NO
experience on Yagi design..

How much ERP do you need for apogee?
