GHz Bands Operation from G4BAO
I'm QRV on 23cm terrestrial and EME - my favourite GHz band, with 400 Watts to a 44 element Wimo Yagi.
On EME I use a SM6FHZ 23cm circular polarised patch feed to my RFHam design 1.9m dish and run 250 Watts
Not QRV on 13cms terrestrial as I've got the 50/70MHz Yagi on the mast instead, but I'm still QRV on 3.4 10 and 24GHz plus 2.3, 2.32, 5.7 and 10GHz EME
