[Hallicrafters] Advice sought on antenna cable type

[Joel R. Hallas]

Waldo,

For 100 W and 40 M, RG-8X will be a great feedline. The loss will be
insignificant and there should be no issue with the 100 W output. I
believe in getting good stuff and would suggest Belden as available from
AES and others. I would use (and  have) Radio Shack as a last resort if
you can't wait 3 days for the real thing.

Make sure that you fabricate a strain relief structure so that the weight
isn't on the connections, else you will have significant loss, when they
break! This can be part of a coax choke, perhaps 8 turns, 6 inches in
diameter, which will keep current off the shield and into the antenna.

I also recommend using good halyards, I use 3/8" dacron yacht braid, to
keep from having to go out in the dead of night with the fishing pole! It
seems expensive, but worth it, IMHO. I also suggest that you have a "down
haul" of light line on the antenna side of each halyard, so if the antenna
breaks (and it will!) you can recover the halyard.

Good luck!
