I mostly agree. Connector loss is minimal. I am all for reducing feedline
loss but to use perhaps 12 feet of Heliax on a 6m beam and then having to
transition to a flexible rotator loop may not be worth the effort not to
mention that LDF4 is more difficult to build a choke with. The original
post did not mention using N connectors, certainly UHF and DIN can be used
with LDF4-50A. That said, I used a number of N connectors outdoors at my
station that was dismantled last year. I only used Amphenol and
Andrew/CommScope connectors and I never had an issue, even in high duty
cycle RTTY contesting at legal limit power. These days I would use DIN
instead but N connectors are not necessarily terrible. N connectors used to
be used a lot commercially and they are pretty inexpensive in the surplus
market

Well, I'll fix that. Connector losses are usually overestimated. If they
are
well mated, loss is difficult to even measure. But what they introduce is
unreliability. Type N connectors are, in my experience, unreliable when
outside with the temperature extremes here in the desert.
