Hello TowerTalkers, The team at PJ4K is planning to put up a 4-element wire yagi on 80 Meters with Inverted-Vee type elements. It will be supported by a rope catenary between two towers, at about 100
Hi Jim, Thanks for your suggestions. I did not realize that Copperweld could break if it gets kinked. Good to know. Regarding the copper split-bolt connectors, I assume that you use some type of anti
John, Can you please share the problem(s) you had with Copperweld wire in the corrosive environment on Aruba? I'll be in the same environment on Bonaire. 73, Rich, N6KT, PJ4K On Sunday, June 28, 20

Hi Steve, Your suggestion sounds very reasonable. One question: I have read multiple times that the electrical connections between the coils and the aluminum tubing can be an issue over time. Has a g
I'm remodeling and putting in Recessed LEDs. The LEDs are quiet with just a regular switch, but a Lutron Dimmer makes a bunch of noise. The Lutron Dimmer makes about the same amount of noise dimming
I Googled: "tensile strength of 304 and 316 stainless steel" and the result shows that the two alloys have very close tensile strengths and yield strengths. I bought a bunch 316 SS hardware, planning
Hi Tower Talkers, It seems that sacrificial zinc is commonly used in boating to stop corrosion. The sacrificial zinc corrodes and "saves" the metal to which it is attached. Does anyone in TowerTalk l
Hi Grant, Thanks for your response. At our station in PJ4, the Hot Dipped Galvanizing is holding up well, but some parts are Electro-Galvanized and are already corroding. Part of the problem is erosi

OK that makes sense. One additional question: We are using AB-105 towers. They are constructed by bolting together vertical, horizontal, and diagonal parts. I am imagining that the use of the urethan
Hi John, On Aruba, did you have any trouble having the Brite Zinc adhere to various HDG parts? We have been using Brite Zinc as well on Bonaire, and it seems to adhere to some parts very well, but fl
