I'm thinking of erecting a rhombic for 20M. From what I've read, the angle at 
the feed point, and the angle at the legs determines the F/B and F/S ratio.  
Also, it seems to be best to feed it with ladder line. In addition, folks 
who've done it say it can be used from 1/2 to 2X the resonant frequency with 
great effectiveness. 

The biggest issue is support it. I don't have a bunch of telephone poles, and 
am thinking of getting a few of the 'push up' masts that could be used around 
the property, but am not sure if these will handle the weight of the wire and 
the intermittent wind loading here in Dallas, TX. 

A few years ago, a bunch of guys and I from the Frankford Radio Club visited 
WOO's receive site at Manahawkin, NJ where they had dozens of rhombics for 
maritime comms. They obviously worked great.

So what say you Talkians? Experiences? Ideas? 

Thanks all!
