[Moon-net] Antenna question

Hello both
I agree that the pair of 18 element yagis will be a good start, and that you
should not attempt to mix these with the 11 element yagis. If you got the
combination wrong you could end up with less gain than either pair. If you
got it right (not easy at all), the improvement over the pair of 18's would
be really minimal.

Hi Andre,
I suggest to only use the (2) 18XXX together in a 2 bay configuration.
With a two (2) port power divider and correct spacing of antenna's this
will do a nice start up for you on EME.
If a simple manual elevation system is used with the 2 antenna's,
that would do a useable EME operation with reasonable effort
and low cost to be operational.
Do not mix different antennas as not desired results will occur.
If a search of the internet is done much information is there to help.
