I also have trouble contemplating having a big wad of heavy cores hanging from
the driven element of a large Yagi where the driven element may be 30 feet or
more from the mast.
Reading K9YC materials it appears that anything less than 5-9 cores just
wouldn't be good enough to do a good job on 14-30 MHz.
Look at the specs on the Balun Designs two core choke wound with RG-400, rated
at 5KW and sealed in a plastic box. Are those specs wrong or is there a
discernible difference between that one and one wound on more cores? Will that
choke, rated at 5 KW, handle 1500 watts in a contest?
One other thing that is difficult for me to understand... Why would anyone
ever consider using RG-58 or relatively huge diameter, heavy RG-213 (requiring
more cores) as suggested in the material when silver plated,Teflon insulated,
higher power handling, stranded center conductor RG-400 is available for very
little money.
I am gathering the ingredients to make some chokes. Do not want to be in
situation where what I don't know DOES hurt me. Heretofore most of my antennas
have had coax wound on a piece of PVC.
I am hoping the end result is worth the trouble and not like an A/B real world
comparison of a tower base with a PE stamped rebar cage design versus someone
throwing in a big handful of rebar pieces one at a time as the concrete was
poured for a guyed tower.
