In defense of the UHF connector the large robust pin, while not constant impedance, which counts more as you go up in frequency, is capable of carrying more current. Also adapters, while convenient usually add loss to a system, again as you go up in frequency. BTW I think a BNC and type N connector are the same dimension at the RF connection point, the only difference is the restraining lock. I know in a test situation a BNC or N with the restraining portion removed is very convenient to just push a cable on in a test set up.

This is true if you are talking VHF/UHF. When talking HF, PL259 is the preferred connector. BTW, all connections placed outdoor should be sealed against moisture. I know of no connector that is water resistant enough to prevent eventual moisture intrusion, a definite performance killer. 73, Keith NM5G From: BVARC <[email protected]> On Behalf Of Gus Bernard via BVARC Sent: Wednesday, November 25, 2020 9:13 AM To: BRAZOS VALLEY AMATEUR RADIO CLUB <[email protected]> Cc: Gus Bernard <[email protected]> Subject: [BVARC] Fwd: [NewHams] RF Connectors / test equipment connectors from WA1MBA See link below frm Dan Marler @ newhams groups.io. BTW, for some time I've been converting all connectors in my shack (& portable gear) to Type N: With the exception of panel connectors on the back of purchased gear, all antenna switches, coax, baluns, ununs, lightning protection and other gear and accessories are purchased with Type N installed. This involves purchasing or making a collection of adapters and jumper cables. The project started because I often needed to make jumpers to interface my own ham accessories (antennas, switches, feedline, etc.) to my issued Civil Air Patrol radios and antennas. I've since spoken to others doing the same thing; if you have a lot of gear (interconnections), I recommend you consider it, too. Type N connectors are better than PL-259 for several reasons, including the fact that they're much easier to assemble properly and are much more moisture resistant when used outdoors. The connectors are slightly more expensive, but I believe the advantages outweigh this slight increase in cost. 73, Gus KG5OFB ---------- Forwarded message --------- From: RATPAC Planning <[email protected]> Date: Wed, Nov 25, 2020 at 2:27 PM Subject: [NewHams] RF Connectors / test equipment connectors from WA1MBA To: <[email protected]> Everything you ever wanted to know about RF Connectors. http://www.wa1mba.org/rfconn.htm ~Dan Dan Marler, K7REX [email protected] _._,_._ ________________________________________________ Brazos Valley Amateur Radio Club BVARC mailing list [email protected] http://mail.bvarc.org/mailman/listinfo/bvarc_bvarc.org
