But I find that to be pretty masochistic!! There ARE special versions of BNC connectors just for RG174/U. I personally LOVE BNCS, and only buy the kind you have to solder, with the threaded clamp on the end. It takes a little effort to comb out the braid and fit the bevel washer, but the result is a rugged, reuse- able and waterproof connector. It's still easier than assembling a PL259 if you could find an UG/1xx adapter to fit, and there isn't any. :-) -- Gary, AB7MY QRP-L #571 Chandler, AZ (near Phoenix)Grid Square DM43BH ------------------------------ Date: Mon, 9 Sep 1996 12:09:25 -0600 From: bfollett@ditell.com To: qrp-l@Lehigh.EDU Subject: [3867] BNC's for RG174 Message-ID: <199609091809.MAA28002@orion.ditell.com> MIME-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Gang: Gary wrote, in response to Phil: <> We have had this discussion before, and the only reference I recall is the AMP RFX for RG174.

These have a built in compression clamp that slips between the shield and center insulation with a cone shape that when the outer threaded part is installed clamps the cable. It is also 100% reuseable unlike the crimp which is one time only. These are made by amphenol and have several part numbers. The ones I use are for RG-174 P/N 31-30220-17 and for RG-58 P/N 31-30220-1 73 Jim K4CGY qrp-l #72 ------------------------------ Date: Mon, 09 Sep 1996 15:21:34 -0400 From: sholla@panasonic.atlanta.com (Holland, Steve) To: bfollett@ditell.com (bfollett), qrp-l@Lehigh.EDU (Low Power Amateur Radio Discuss) Subject: [3875] RE: BNC's for RG174 Message-ID: <1996Sep09.152000.1619.47703@ntserver.panasonic.atlanta.com> Mime-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" I have at times not had the proper crimp tool or for some reason ( engineers preference) not wanted to crimp. What I have done is assemble the connector as normal and add a small piece of heat shrink before assembly. Then after pushing the crimp tube over the coax braid I used a high wattage solder iron to heat the tube. With a little care this can be done with out melting the center conductor. The heat shrink then covers the braid that is visible above the tube. I always trim the jacket back so I don't melt that also. I hate the smell of burning plastic. This has worked well for many different coaxes and adapters from SMA to BNC and even N connectors. All it takes is a little care and it should work for you to. Hope this helps. 73 de N9HXX/4 Steve N9HXX/4 sholla@panasonic.atlanta.com QRP-L # 555 NNN0ONT-T ---------- From: bfollett[SMTP:bfollett@ditell.com] Sent: September 09 1996 14:18 To: Low Power Amateur Radio Discuss Subject: BNC's for RG174 Gang: Gary wrote, in response to Phil: <> We have had this discussion before, and the only reference I recall is the AMP RFX for RG174.

For those who want to attempt this death-defying feat, Jameco has an inexpensive ratcheted crimp tool with multiple dies for RG-58, RG-59, RG-62 and fiber cable as well as RG-174. It is on page 45 of the June/July '96 catalog and carries the Jameco part no. 114534. The best part is the price - $19.95! I've seen the identical tool on sale elsewhere for $34.95 listed as a "discount" price. Can't vouch for its worth with RG-174, but it's pretty good for RG-58. Jameco also has good prices on the crimp connectors. Usual disclaimers apply, some assembly required, batteries not included, I'm from the Government and I'm here to help you, et. 72/73, Joe E., N2CX ------------------------------ Date: 09 Sep 96 20:39:56 EDT From: Craig LaBarge <74740.3166@compuserve.com> To: QRP-L Mailing List Subject: [3896] Re: RG 174U Message-ID: <960910003956_74740.3166_EHB174-2@CompuServe.COM> Ron Giuntini wrote: > Best connectors for RG174U??? I have had real good luck using shielded RCA phono plugs. I use adapters for other connecters (e.g., PL-259), as required. Certainly not the best, but a very workable arrangement. Cheap and easy to install. 73, Craig WB3GCK ------------------------------
