[MRCA] Antennas

[Al Klase]

Hi Gene,

Short elements are 24' 9" and the long ones 36' 11".

I've always been confused by the disposition of these elements.  The two 
short ones are connected to the center conductor of the mast, and angled 
at 90 degrees to each other.  The long ones are connected to the outside 
of the mast, angled at 90 degrees to each other, 180 degrees around from 
the short elements.  So the antenna seems to be crossed Windoms rather 
than crossed dipoles.

I'm not sure how important a matching network is with a true field 
radio.  They'll about load a wet noodle.

Regards,
Al

I inferred their lengths for my earlier modeling efforts by taking the dimensions for another Ham's homebrew equivalent.  However, I never actually measured the lengths.  Harris's web pages on the antenna cleverly do not give dimensions.
