Some advice to take the effective boom length of the antenna in wavelengths and take the square root of it. This is the optimum stacking distance of your beams in Wavelength. I think it is way too ge
Thanks, Jiri, for showing up as I hoped. I had this 6/6/6/6 @13/19/25/31m of yours exactly in mind when I pointed out that I might not be the only one stacking them so close. Have you found any diffe
As I have found the presence of the undriven antenna is effecting the gain and F/B a lot. Actually in a stack of two the lower undriven antenna decreases the gain of the upper one by about 1db if tur
Actually when I meant to maximize the forward gain then that implied only giving up maybe 5db front to back. Say, from 25 to 20. And usually with those OWA stacks I modelled the F/B got maybe worse o
Is it a good idea to make a HF antenna feedline from several shorter pieces of coax by soldering or in any other way connecting them together without proper connectors? Having RG 213 and LDF 4-50A in
Thanks to everybody for answers to my LDF 4-50A splicing question. Great ideas really. But splicing two pieces of RG 213 without connectors is also a issue of interest to me. Would it be a very fooli
Stan, this stack should work! I have 2 fullsize 3 EL yagis (40' boom) stacked at 140' and 70'. It is sometimes difficult to notice sharp effect on RX but on TX the stack is the best 99% of the time!
Just a short note on real life A-B. I have two identical 80m Inverted V Dipoles. Both with 45 feet high apex. One above the roof of the countryside house with some 60 feet of feedline and the other a
Hi, I am refurbishing my shack and want to place a grounding panel into the wall and to bring all my antennas into the shack through it with bulkhead adaptors. Just want some advice. 1. Is copper pla
Absolutely agree, I am using Dynamix for guying my 150 feet tower with 2x3 el full size 40m yagis and 4 large tribanders. Dynamix is a combination of Dyneema SK75 and Aramid fibres (Kevlar) used in y
Hi, I have got my full size 1/4 wl aluminium tubing 160m 4 Square up and running with Comtek hybrid coupler. I use basically ground mounted verticals (isolator about 1m from ground) and intend to put
Thanks Tim, I was also adviced to avoid radials crossing if they are not insulated. Well, at the end the difference is small if any, that's true. So as I have insulated wire, I will maybe put still a
What do the beverage experts think about fixing the elongated beverage in the forest by running a few turns of the wire around the nail or branch that is used for it's support? Do you think it affect
Thanks to everybody for sharing their thought on wrapping beverage wire around the branch or other support. Great ideas indeed! Nobody said it would matter electrically, many have wrapped them for ye
I have right now on 80 meters 3 element coil loaded Optibeam Yagi at 36m height on rotating tower and also full size 4 Square with 64 ground mounted 1/4wl radials per each tube vertical using Comtek
I have 4 stack of JP 2000 tribanders on one of my towers. Those are interlaced 10 element beams (3/3/4 elements respectively on 20/15/10) with single feedline and boom of about 7.5 meters. I find the
