connectors.
|
No problem what type - just use only high quality ones. For instance in Frieadrichshaven this year I have found only ONE (!!!)seller with usable PL connectors (at 5.5 DM each).
I have burned dozens of both. On PL usually the female is a problem - bad plastic and often not tight enough. The male should be teflon. The N is too tiny for HF and what you get from better impedance holding is negligible up to 144 MHz.

N connectors
|
|
If you use the correct kind of N male connector, like an Amphenol 82-3312, you won't have a problem. Those have captivated center pins, held in place with two teflon spacers. N connectors commonly available from surplus that have the center pin simply floating on the center conductor will pull apart. It is physically impossible for a captivated male connector to pull apart!

UHF PL259
|
Why do I use UHF (PL259) connectors? Because it takes about 30 seconds to strip the coax and solder a uhf plug. But it only takes 90 seconds for a N-connector I hear you say?! Oh well, just bone-lazy I suppose!! :-)

UHFs
|
IMO, N connectors are much easier to assemble *incorrectly*. The common occurrence of their center pins not staying where they belong is hard (impossible) to inspect/detect.
UHFs are robust and there are only two parts. The fact that one literally screws the UHF over the cable's jacket makes for an excellent mechanical (even weight-bearing) connection as well.
Just keep the water out!

Depends on application
|
It depends on what I'm trying to do. For station interconnects, it's almost all SMA for low-power. They're becoming really cheap, RG142 cables have em pre-installed in neatly bundled lengths. . nice for connections to preamps, beverage switching, VHF+ transverters. Where power is involved, either UHF for below 30MHz, or N (sometimes 7/16 DIN) for 50MHz and up. Again, it's based on surplus availablility. Many 1/2" Superflex jumpers now have 1-N(Male) and 1-7/16 DIN. Easiest to get the Female sockets & use them!
I use 1/4" Andrew Heliax or 1/2" Superflex to the antennas from the main feedline. Almost all use N-Connectors.

Don't use N's on vert runs
|
KN8Z used N connectors everywhere. The first winter in Ohio after he installed his HF stacks all of his antennas went dead. The vertical runs of RG-213 and RG-11 that were terminated in N's contracted in the cold and the pins of the N's disengaged.
We replaced them all with UHF connectors in
the cold on the tower. Not fun.
N's are fine for hardline, but never again on outdoor sections of RG-213.

PL259 v N Type
|
No matter how good quality your PL259 is (and usually only the pressure sleeve type are any use), it's only as good as the next stage in the line, and that is usually a poor fitting and poor surfaced SO239 socket. Ditch them all and use pressure sleeved N Types. They interlock better, are less lossy, and are much closer to the normal required 50ohm.

Forgot PL's forever
|
If you really want to be a little bit technically serious, forgot PL forever. Especially cheapest types of PL's with plastic isolator and bad galvanization.
If you are legal power station, N will be the best solution. Almost the same price, equal good quality from different producer and you can find it for all types of cables � RG213/214, 1/2" , 7/8" etc.
I have PL's only on my TRCV's.

PL? N?
|
|
I use neither type.. my outside antenna is a doublet, fed with open wire... no plugs neede ;)

Depends
|
|
I have probably 200 UHF connectors outdoors, and about 100 N connectors outdoors. At 144 MHz and up, it's all N connectors; below that it's all UHF connectors. Properly installed and applied, either type is fine. For joining Andrew Heliax segments to make long cables (mine are all over 300 feet), I use back-to-back EIA flanges because they're much stronger than back-to-back N connectors and Andrew L45Z splices are basically nonexistent on the surplus market--EIA flanges are readily available.

I use PL's below 30Mhz and N's above.

N-Connnector
|
This connector is very good for UHF-frequencies because it has not so much less.And sooner than this type of HF-connnector is waterresistant.
