[MRCA] static discharge reel for antenna

[B. Smith]

Eugene
First I would not take a chance on having that lumped impedance secretly 
hiding inside the reel, too unpredictable. The tuner might even 
recognize that as the antenna and ignore the wire. :-)

I would take a wire the length of the pole, cut off the rest and do a 
nautical splice with a couple of feet of nylon rope.  The nylon rope is 
now your insulator.  Use a standard wire nut to hook the feed line to 
the vertical wire.  The whole thing can wind up inside the reel. Remove 
the wire nut prior to winding up the wire.   :-)
  See attch.
You did not mention what material the mast is made of.

On QUESTION: The second type of reel (with insulated cable) seems to 
come in 50-foot lengths. This means that about 25 feet will remain on 
the reel in a loop about 3-4 inches in diameter. I am worried that this 
will create an RF choke and reduce the performance of the radiator. Or, 
it might make some kind of base loading, I really don't know. Of course 
an alternative would be to cut down the cable to 25-26 feet or so, but I 
was wondering if anyone had thoughts about the effect of having this 25' 
coiled before the vertical radiator. Thanks for the bandwidth of a very 
wide band email!   73 Eugene W2HX
