[TowerTalk] OptiBeam OB2-40M

[Michael Tope]

One of the radio clubs I belong to is interested in buying an OptiBeam 
OB2-40M two-element 40 meter Moxon Yagi. Optibeam is kind of vague on 
wind survival specifications. Their website indicates "Windload at 130 
km/h           430 N / 0,54 m² / 5,9 feet²". To me that implies the 
antenna is designed to survive 130 km/h winds (80.7 MPH), but it doesn't 
actually say that. The antenna is going to be installed at a Southern 
California QTH at a fairly low elevation, so icing is extremely 
unlikely. However, the antenna will be installed on a high narrow ridge 
that lend itself to very high uneven (shearing) winds when we get the 
occasional winter storm or Santa Ana wind condition.

Anyone out there using one of these antennas? I am curious what you 
think of it in terms of performance and reliability?

Thanks and 73,
