John, Does it mean that you bore a hole up to 8 to 12" wide and 4 to 6 feet high, put a beam inside, and fill the hole with concrete? How do you determine the length and the size of the hole? Ignacy

There were quite a few reports of failures of Comtek units usually attributed to bad relays. Recently my Comtek 2 stack unit was becoming intermittent. It has sealed Potter-Brumfield relays so no wat

I received mine a year ago. It was not round. Carl sent a replacement that was more round but not completely. I installed it tightly and it moves so far although sometimes a few degrees away. Ignacy

64. [TowerTalk] 16om vertical and the number of radials (score: 1)
Author: Ignacy Misztal <no9e@arrl.net>
Date: Fri, 2 Dec 2022 09:25:27 -0500
Do more radials on a 160m vertical bring more improvements than shown by simulation? Most simulations show that going above 32 radials on 160m brings minimal improvement, say 1 db to 2 max. Even for

I had a roll of 2000ft 18GA enameled wire and I spread it as radials towards North. Complimenting current 36 radials. The impedance dropped 0.5 Ohms, indicating a failure. In the ARRL 160m contest a

I had the W9INN dipole for 40/80/160 with two sets of coils. The bandwidth on 80 and 160 was about 30 khz. Compared to a ladder line fed 80m dipole, the W9INN dipole was so much down on 80 and 160 th

I have a 100ft 45G with 3 sets of guys. I would like to set up 60ft of 25G to carry two small beams. A few questions. If 25g is set on a hinged base plate and laying flat on the ground, can 45G be us

Many useful comments. The tower would support 2 tribanders like JK C3 fixed to SA and OC for multiplier hunting. Until a bigger tower is erected. 4 guy wires seem a good idea. Ignacy NO9E ___________

I have a ham radio property in a rural area. Fairly quiet. My neighbour informed me that a 1000 acre solar farm by Green Bolt is coming within a quarter mile. I am contemplating another tower but I a

I am trying to install multiple tribanders like C3 on a single tower for fixed directions. What is the minimum vertical separation so that gain would not be much affected? Ignacy NO9E _______________
