UHF connector to sheetmetal

[mainetrunk]

Hi guys, I am playing with HF feqs and what not, I picked up this UHF connector 10 UHF Female Jack SO239 Panel Chassis Mount Connectors | eBay for experiments. My question is -- if I have a 10 inch by 18 inch sheet metal piece, if I drill all 5 holes, and attatch the UHF connctor to the sheet metal-- would there be loss? Is stainless better? I would have the bolts going thru the sheet metal going to connector and bolted WITH stainless washers and nuts to hold it together.. Also, what do I do with the BACK side of the connector? Front hast the threads, back is that littile nub.Is that the ground? . I intend to put the sheet metal screwed to a wooden post while I run wires off the bolts, ALOT of wire, 4 holes, 4 wires.. Thanks, Ron.... This new Alinco is too much.....

The center pin (nub) is the center of the coax, ground goes to the metal via a bolt holding the bulkhead mount in.

Yes, I'd use stainless, may last longer.. Also give a thought to water proofing.

4 ground holes? This is a temporary TUNING station. How do i put wires on that center pin? Too many? No, just different fields... Thanks

No. 4 mounting holes. You only need 1 ground per coax.

Solder the center of the coax to the center pin of the connector. Connect the shield (braid) to a bolt.. I'd use an eyelet that's been both crimped and soldered to the braid.

RX only or TX.. SOLDER

Also, I'd keep the soldered side away from the weather..

Is there such a thing as too many radios??
No, I want 10 more p25 scanners, 5 more receivers. Icom IC R75 Wide Band Base HF 50MHz All Mode Receiver | eBay something like this
