Re: [amsat-bb] Wimo Antennas

["Mark L. Hammond" <mlhammond@xxxxxxxxxxx>]

Gary,

A couple of years back, I bought a 40 turn helix for 2.4G and a 20 turn helix for 1.2G, both from Wimo.  Both were very well made.  Shipping was expensive!!

The 1.2G helix has been on the array since then---I've made contacts on both AO-40 and AO-51.  I sold the 40 turn 2.4 helix at a hamfest last for a cheap price--I've become quite a believer in the dishes!  A 24"/60 cm dish is quite a bit more antenna...

You can hear AO-51 on a lot less than 40 turns---the G3RUH patch alone (8.5 dbic) is sufficient when you're in the clear!  I believe Mike KE4AZN has worked it a few times on something like a 2-4 turn helix feed.

As I grew accustomed to the microwave stuff, now I'm dreaming about a 4-6' dish with a tri-band patch feed :)  

73,

Mark N8MH
