And conversely (not that I'm an expert topbander), it might be true that a good DX antenna is more than *adequate* for close in contacts in most situations. -Steve K8LX On 08/24/23 6:28 PM, Mike Waters wrote: Contrary to what you hear repeated on the bands year after year, what Jim said is *e

Wow, even though I haven't been very active on 160, I'm pretty sure Herb was one of my very first DX contacts in 1964 on whatever band, probably 15. Seems like he was still posting on the reflectors just a few days ago. Very Sad, -Steve K8LX On 04/29/20 14:21 PM, d...@np2j.com wrote: It is wi

Any connector with a captured (non-solder) center pin will accomplish this, such as the Times EZ series (EZ-400-NM, etc) or many of the corrugated hardline connectors. As long as the connector was not installed in cold weather with the center conductor pushed in as far as it will go. If the cab

It's doubtful that 4.3-10 will ever be popular for larger cables, because large diameter feedlines in the cellular industry are no longer being installed. It's all Remote Radios behind the antennas, and short 1/2" jumpers. So be happy with N or 7-16 for your main lines. I recommend 7-16 of cou

Well here's the advantage of captivated center pins: the pin is NOT bonded to the center conductor. IOW, if the coax center conductor shrinks a bit, it can slide in the center pin and the pin stays put. And that's exactly what you want it to do - especially with an N connector. -Steve K8LX O

I've just recently been reading up on Waller Flags, and am certainly no expert, but my impression so far is that an HWF (horizontally polarized flag), mounted up in the air on a tower, should be less affected by tall vertical thingies in the area; and less prone to local noise in the area which
