Baluns - Type 43 vs. Type 73 beads, etc.
A couple of questions:
1. I have some Type 43 beads that will fit over RG8X that I am putting
up. The OD is about a 1/2" inch as is the length. Will this work for
~3.8Mhz and how many of those beads will I need to use? I can get type
77 in the right size, would there be any advantage to using type 77? I
would like it to handle legal limit - and I would only run that if the
SWR was under 2:1.
2. Why do most 1:1 baluns use that section of RG-303 coax with the
small type 73 beads? Is that a teflon coax that can handle heat
better?
Thanks!
