221. Re: [TowerTalk] Selecting Coax connectors (score: 1)

In my earlier note about DIN connectors and stranded center conductor braided cables, I should have said they need a *separate* center pin - IOW, loose in the bag before installation. The center pin

RE: crimp-crimp PL-259's - I've never used them, only the crimp-solder type. So I have no idea why the warning against soldering the center pin on those connectors exists. AFA DINs for stranded cente

Connectors *can* be waterproof (those that have internal gaskets). However experience tells us there is no guarantee that they are, and that's the rub. So commercial practice is to always add additio

Gerald, I'm not aware of any foam filled cables that can be pressurized. Pressurized corrugated cable is normally of the air dielectric variety - the Andrew HJ series being the most common but there

Well if it's made for LCF78-50, that's the safest one to use. Other connectors might be usable if the center conductor pin is the right style and size. I watched the video, it's a fairly typical inst

John, FWIW, I find LDF4 very reasonable to handle. Yes, and so does almost everyone who uses it on a regular basis. It's very robust, and takes some serious abuse to damage it. I've seen both LDF4 a

Yes it is. It's weird how they include the word Heliax in the title since it's not Heliax. But even with the aforementioned caveats about smooth wall hardline, the stuff has one really valuable chara

Hmm. All I can say is we install much larger pieces of assembled tower than R55 (and 50' pieces of monopole weighing many thousands of pounds for that matter), and crane operators seem to have no pro

The L5 connectors are only for LDF5 Heliax, which has a smaller center conductor that AVA5. You need either an AL5 connector, or an A5 connector. The AL5's are more common. -Steve K8LX Ive been tryin
