I believe that was the failure mechanism in the wind-induced collapse of K4JA's 200-foot AB-105 tower used for his stack of 40M beams. I worked (in a minor way) on the replacement with heavy-duty AB
Maybe 15 years ago, some of the big station guys around here put together a group buy of several thousand feet. Far as I know, everyone is still using it and is well satisfied. I helped install one
In fact, I believe F12 in later years made the 40M single-band antennas (called the Delta line) with coils in place of the linear loading. That said, I had one up at 104 feet for 15 years with the o
Frankly, I'm curious why it is still there. Bart, why not stop by and ask the owners? The house shows signs of a significant evolution over the years, essentially doubling its footprint. I like towe
Another option worth considering are duckbill drive-in anchors, particularly for a relatively small installation like the AB-621. See <https://www.westechrigging.com/shop-by-brand-duckbill.html?gclid
You always have to read the small print. My State Farm home insurance covered a $2000 lightning hit on my accessory structure (tower). 73, Pete N4ZR Check out the Reverse Beacon Network at <http://r
I thought people might be interested in a recent experience. I blew the center 4:1 balun on my Carolina Windom, which has been a very effective antenna for 80 and 40. Took it apart, but since this
I've used Yaesus (800 and 1000) for 25 years, though never with your likely size of antennas. Never had a failure except one direct lightning hit. Love the control box and the 450 degree rotation 73
I think it's an energy-absorbing fall-arrest lanyard. amazing - they get almost a kilobuck for the full-body harnesses they sell. Other sellers think $200 is more than enough. 73, Pete N4ZR Check o
I just blew up the line isolation choke on my Carolina Windom - not good timing right before the IARU test. I have now blown both the balun and the line isolator on the antenna. The antenna works r
On advice from another of the frequent online gurus (that is, not K9YC), I bought a MyAntennas choke balun to replace the fried line isolator of my Carolina Windom. It's pretty, and its cylindrical
That reminds me, the Myantenna line isolator I just installed had a tiny weep hole on one end. It would have been awfully easy to install upside down. 73, Pete N4ZR Check out the Reverse Beacon Netw
FWIW, Tony, I have an 80-10 meter Carolina Windom with the vertical radiating section with the center at about 45 feet (ends somewhat higher) and it works really well. However ... while I don't thin
In my old station, someone came up with this idea - instead of an actual loop, start with the rotator at mid travel and wrap at least two *loose* turns of RG-213 around the mast, then connect to the

I've discovered that one of the PL-259s on a pre-made RG-8X cable shows carbon tracks inside and arcs when I try to use it - I run full power through the junction on 40M and lower bands. Am I right t
On the other hand, if you guy the pole up ten feet or so, then the lateral forces at the bottom are really trivial, and almost anything from a ground rod to a T-post will do fine. Enough time has pas
