Subject: [Antennas] Old TMC Antenna Parts

I have the following components to an old TMC wire antenna system and would
like to sell them, preferably as a package.  But I will entertain separate
needs and make up a list if there is enough demand.  I am researching as I
have time to put some kind of value on them.  To a TMC enthusiast, it would
seem they would be attractive.   Anyway, if you are interested, contact me
and be patient.  I am on "digest mode" and very busy right now.  My goal is
to generate some gas funds for a hamfest trip or two as well as to get the
components where they might be useful and appreciated.  Some pictures are
available and will be sent if requested.
 
These parts were part of either two Rhombic antennas or one "V" shape
antenna.  I can send a sample sketch of what an antenna set up would have
looked like.  Basically coax  went out from the transmitter shack to a point
at which the antenna ladder-line was desired.  At that point, TMC used an
adjustable balun to feed the ladder line.  The ladder-line then traveled to
a point at which the Rhombic or V Shape antenna began.  Half the ladder-line
went in to the antenna left side, the other half went to the right side.  On
a Rhombic, when the antenna wires came back together, one antenna RF
dissipator was employed  to terminate it.  On a V shape, each terminating
end had an RF dissipator.  I have enough components to do either antenna.  
  
The question "how much" at this point is an open one.  I don't know yet what
is reasonable to ask.  The stuff might be worthless or it may be worth
something.  Your own estimate is welcome.  I do need two or three 7' Bud
IEEE open frame relay racks and would  trade for same.  
  
One item below (the coax) is probably a pick up only.  All located in Baton
Rouge, Louisiana about 3 miles off the I-10 E/W Interstate. 
  
Here is what I have:
	(2 ea) TRK-500 TMC Antenna Balun boxes with 50 ohm input/100-200-600
ohm output  (each TRK-500 has a large RG-164 size female connector and the
matching male connector is on it. The female plate could be changed and an N
style put on it) one is very nice, the other had a gasket breach and will
need to be cleaned up; both need new  weather gaskets
 	(1 ea) Spare balun for above TRK-500 
 	(2 ea) TER-500 Antenna Dissipators (Terminal end; one used with
Rhombic, two with "V" shape) 
 	(2 ea) 40-50 foot (approx) lengths of Amphenol RG-164 coax, each
with one connector on one end (these could be spliced together using
Scotchcast 2130)  RG-164 has an HV rating of 10KV 
 	(3 ea) 8' (eight foot) "Chance" fiberglass guy insulators; dowel pin
knuckle on each end 
 	(4 ea) 4' (fout foot) "Chance" fiberglass guy ends (unfortunately 2
long 8' units were cut in half-these could be used for the Rhombic side
pass-throughs) 
 	(2 ea)  There are also two large roller inductors which I haven't
figured out whether they went with this material or not.  6 - 7" diameter,
maybe 10 - 12 turns; US Navy class inductor tuners.
  
Again, some pictures are available on request (be patient).   Feel free to
forward this email to any other appropriate group.
 
Thanks for the read,

John W5JV
