1. [TowerTalk] Stacking dissimilar antennas (score: 1)

Bob: You want to use identical antennas as N3RR pointed out. Also, to insure equal currents, you want to use feedlines from the antenna to the common point (t/b/l switch, etc) that are equal AND a 1/

Bob: Change those references to "1/4 wave multiples" to "ODD multiples of 1/4 wave". Usually a good place to put a 1/4 w. of 75 ohm (or whatever) for matching, along with equal lengths of 1/2w. multi

Don: Odd 1/4 wave multiples force equal currents in the antennas, which helps preserve the desired phasing and reduce pattern degradation. This is true whether you use 75 ohm for matching or have a 5

Larry: I don't think you want to hook your tram line to the mast unless it's a real small beam on a short tower. There is a LOT of tension on that line. Hook it to a tower leg at the top of the tower

Ok, you got 2 things on me: guts and space. I quit tramming 'cuz I didn't really feel comfortable with the setup, and didn't have the clear ground space to lay out the antennas. I did do some smaller

Stan: Yeah, I didn't get everything in my head onto the paper. I don't like to trust a thrust bearing to support the weight alone without a fail-safe backup. I guess I shouldn't have used "designed"

I'm installing a short (300') beverage for EU to be used primarily for 80m, occasionally on 160, and have some questions for the collective. My main goal is f/b, to eliminate T-storm static from behi

So, is this why I had a difficult time working Europe on 80? It was like a one-way mirror in the Atlantic...I would answer loud European CQ's, and they would CQ in my face. 40 was great! Why does th

Lee: Lightning. I used to blow them regularly until I learned to disconnect the control wires when not in use. Not necessarily a direct hit, but in the neighborhood. If the element "vaporized" into p

Charlie: Good chance there are a couple of teeth missing on the large ring gear. Did you have the antennas "parked" at 285 deg. for a while during a big wind? I'm sure the experts will chime in, but
