[QCWA] Slightly off topic, antenna sharing.

[Don Tucker]

Amphenol offered a line of folded dipoles back in the early 50's, still have 
one in box someplace. Were in common use. Don't know when they got out of 
the ham business but probably not long afterward.

Jeff,

Folded dipoles are a lost art.  Back in NYC I used one cut for 6
meters in a short term rental (circa 1961) made of el cheepo 300 ohm
TV twinlead -- including the feedline.  Balun was RG-58 right at the
radio (Clegg 99er) and I worked 19 states with it on 50.4 MHz AM
during that e-season.  A similar standard open dipole fed with RG-58
could not hear half the stations the folded would.

And then of coarse there was the famed Hi-Par 5 element 6 meter beam
that used a 300 ohm driven element with either a 4:1 (for 75 ohm) or
6:1 (for 50 ohm) coax feed.  As 75 ohm coax was mass produced as TV
lead in, back then 100' of Belden RG-59 cost about $5 while 100' of
RG-58 cost $15 or so.  And the 59 offered less loss.  So it was not
uncommon to see a Hi-Par 5 el fed by RG-59 shoved into the SO-239 on
a Gonset Communicator or G-50 and the like.  Tubes and Pi-Network
output did not mind 75 ohm coax.

As an aside:  Last year on a trip back to Brooklyn I passed the place
where one ham I knew from back in the 1950's and 1960's  lived while
a teen and young adult.  He and his family had moved away some 4
decades ago, but that old 5 element Hi-Par and CDR AR-22 rotor was
still mounted on the roof where it had been for the better part of
half a century.  Says a lot for the way things were constructed back then.

Its to bad W1NEV never licensed anyone to continue producing his
designs and the only story I ever heard -- going back maybe 2 decades
that his family has refused to sell his designs and patents for his
Yagi's and famed multi-ring 6 meter loop for reasons
unknown.  Whether the latter is true or not is however mainly hearsay.

One of my NYC friends now living in Florida says he has a like new 3
element version he used for hilltopping back in the 1960's but will
never let it go.  He says its a gem thats impossible to replace.
