[Antennas] Old TMC Antenna Parts

Sun Jan 15 10:07:14 EST 2012

 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,
