Has anyone tried that stuff called "Stuf" that's sold by AES, HRO, etc. as a coax connector filler/sealant? Sounds like you use it just like you would use the silicone grease others have been mention
I know how to install a PL-259 (though I still hate the damn things) and I like Rod's method except for disagreeing about soldering the braid on ANY type of low loss coax (RG-8 foam, 9913, LMR-400, e
Doesn't make sense. How can something on the outside of the shield cause SWR bumps? Also, why would Times Microwave (the LMR cable folks) and others sell the stuff if it screwed up the impedance of
Just a suggestion: as an alternative to sheet metal screws for securing element sections, try aluminum pop rivets. The screws draw the soft aluminum from one element section up into the other elemen
But how many Watts? My Weller station get's mighty hot too, but it won't hold a candle to my ancient, dual headlight, 250 Watt gun when it comes to soldering PL-259s (which I only use with the great
Here at K0HPS we use a separate antenna farm for each radio. You wouldn't want two guys to accidentally switch their radios onto the same three-stack of 80 meter monobanders at the same time, would
Hi Chuck, A couple quick questions: Can you put anything on the roof or around the outside of the building? How do you feel about wires running around inside your apt. up at the ceiling and down on t

Hi Tom, Thanks for the lesson on "Pop" rivets. I'll have to see your demo some time. Will you be doing it at Pacificon? Also, do you have any part numbers for the rivets you recommend? Or perhaps the

Hi Chuck, OK, here's one idea for your inside-the-top-floor-apartment all band HF antenna. As you will be using a tuner, you really don't need to worry too much about exact lengths. Generally, longer
Hi Martin, I've had that problem with "UHF" connectors too. It's not the pitch of the thread, but sometimes the shell is too long for the number of exposed threads on the SO jack. Other times it jus

Sure will, but you can cure the problem with some heavy aluminum foil, screen or whatever you can get to stick to the plastic under the antenna. There's a product called Ideal (I think that's the br
Dear Mr. Manufacturer: With all this talk about attaching PL-259s it makes me wonder: Why do we have to put up with "UHF" connectors? The only good way to install them is with a crimping tool, and th

Just wondering... has anyone else run into the requirement for seismic load calcs before a permit for a tower will be issued? US Tower tells me they have never heard of it and yet the county engineer
