Jacques: I don't think Beverage construction is out-of-topic at all--quite the contrary! The most commonly available "ladder" line is the "450 ohm" window line. But this line has single copperweld wi

There are AC types that won't have the periodic pop. I recently "electrified" a metal bird feeder because the raccoons were raiding it nightly. If there is no leakage then the line is RF quiet. With

Sounds like you have done your homework, Charlie! BTW I also noted a version of that insulator with a 5" neck, similar to the single-wire extended insulators I already have bags of. Garry Hi Gary, et

I regret disagreeing with my friend Earl, but I just purchased and installed EZNEC 4, and it, like EZNEC 3, uses the NEC-2 engine. EZNEC 4+ offers more segments and a few additional features, but als

I modified a 100 kHz Loran loop to 1.85 MHz, mounted it on ski racks on my car and cruised the neighborhood looking for low frequency noise sources--those rolling off below 4 to 7 MHz, which are not
