Update September 2009

A new Optibeam OB5-20 has been put up on a 18m crank-up / tilt-up tower furnished by LA3ZPA.  The antenna is a 5 element OWA beam with 15.1m boom length, 8.5 dBd specified gain, 26.5 dB F/B and 24.6 dB F/S.  SWR is excellent over the entire band.

Significant pile-ups and "tnx first LA" from several stations in western US on the first day of operation indicate that the antenna works very well.

Now, we are anxious to see if the Optibeam will withstand the severe wind conditions on our QTH.  We are entering an exciting contest season.
