ORIGINAL MESSAGE: -- REPLY FOLLOWS -- May I ask how you terminate the ends? Is EHS flexible enough to wrap around a thimble and use clamps or do you need to have swaged ends? Or something else? Thank
ORIGINAL MESSAGE: -- REPLY FOLLOWS -- I like the ones made by Daiwa and some other companies that copied the design. They carry the legal limit and ground the unused port to prevent the kind of damag

ORIGINAL MESSAGE: -- REPLY FOLLOWS -- Have you tried the method of soldering the braid where it enters the rear of the connector, ignoring the holes completely? It works great and allows visual inspe

ORIGINAL MESSAGE: -- REPLY FOLLOWS -- In the years after WW2 they were cheap, plentiful and very, very powerful. One drawback is you have to make your own position indicator. I haven't priced them la
ORIGINAL MESSAGE: -- REPLY FOLLOWS -- I agree. Teflon has a nasty characteristic called "cold flow" which means it will deform over a period of time due to simple mechanical pressure. While I have no
ORIGINAL MESSAGE: -- REPLY FOLLOWS -- In the aerospace industry our policy was to not use Teflon insulation unless we needed its specific properties. In a PL-259 Teflon is overkill. As I said, use it
ORIGINAL MESSAGE: -- REPLY FOLLOWS -- Baluns are not resonant circuits, but traps are. Baluns do not have the high circulating currents that traps do and that is one of the important differences. A t
