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

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

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
