Hi Marinus,
The male "UHF" connector is a PL-259 and the female is SO-239. At MF and
HF they are fine if they are quality versions and are installed
correctly and kept clean and dry. You see a lot of terminations (dummy
loads) with "N" connectors, because many of them are rated for much
higher frequencies than SO-235/PL-259 are very good for. They are
typically used as the load for reverse power on a circulator between a
transmitter and a filter cavity in a UHF or VHF transmitting system.
Professionals stay away from PL-259/SO-239 connectors. Good connectors
(BNC, N and others) are usually three or four times more expensive than
"UHF" connectors. If you are staying with smaller cable such as RG-58
and RG-59, BNC is a good choice. If you stay to power levels that can be
handled by RG-58, then BNC connectors will also handle it.

After an absence of 24 years I got back into ham radio. Lots of chances have
happened in the intervening period and back int he 80's the only connectors I
could lay my hands on was either BNC or PL239.
When I was browsing around looking for dummy loads I noticed a lot of N
connectors on these.
I have only a few cables at this moment but more gear is due to come into the
shack and I am not exactly thrilled with the use of the PL239.
Out of the whole range of connectors that is available which are a better
solution to move to than the cheaply (perhaps better mentioned: junk quality)
PL239?
Main use will be for in the shack between equipment so I prefer to stay away from the
"heavy" cable. The antenna is being fed with twin wire.
Many thanks in advance for your input, 73, Marinus, ZL2ML
