My ham radio antennas are all 50 Ohm designs, but I do cheat on the receive loops and repurpose old Echostar cable around the house.

And an old Radio-Shack Ungar 45 W for the occasional emergency. There are situations where The Weller gun comes in handy, when the other 2 don't get hot enough. Failing all 3, we have the trusty Bernz-O-Matic.

It doesn't wet well with my ancient 'non corrosive flux' Multicore 60/40. A touch of flux and it solders beautifully. Cheers -- Syd

What's wrong with F-connectors? There are zillions installed on indoor and outdoor CATV installations with no failures or issues. Certainly there are connectors with better specifications, but for the intended purpose and cost ($0.30/ea), F-connectors are more than adequate. The only real problem I've found is the wide variety of cables claiming to be RG-6/u. Making a connector that will fit all these RG-6/u mutations is tricky, but T&B has done a decent job with their "red" SNS1P6U Snap-N-Seal connectors: <http://www.ebay.com/itm/221344116756> So, what's wrong with F-connectors and what would you recommend the CATV industry use instead? -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

I can't help that you are absolutely clueless about the technology. There are millions of miles of Rg/6 with F fittings used into the UHF range outdoors with a very low failure rate, and lower leakage than some BNC connectors. If they were crap, they wouldn't be allowed to use aircraft and commercial two way frequencies. A couple bad connections in a cable system can shut down an airport, or the local fire and PD. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.
