I have found that wrapping things like that tightly in aluminum foil stops the problem. However if it is one that is wired into the house electrical system you may also need a few ferrites on the pow
The operators that come from the city up here have found that the best antennas for urban contesters belong to friends in the country. David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://ww
See below. maybe something salvageable in the tracy ca area?? Fixed links: http://www.insulators.com/pictures/?id=167860012 http://www.insulators.com/pictures/?id=167858696 http://www.insulators.com/
My only question, why go to all that trouble to stack like that with elevation control and not also provide for polarization rotation??? A few more motors, some fancy gear drives, and tilt them verti

Sounds like front end overload or some kind of mixing inside the radio. Does your tuning/matching circuit on the vertical have some narrow band characteristics that is rejecting broadcast band stuff
Its probably not because of my tower farm, but my property value has gone up every time its been reviewed for the last 23 years. Having towers sure hasn't lowered the value, at least according to the
I am trying to decide what to use to build 4 new 80m verticals for a 4-square upgrade here. My criteria are: 1. full size 1/4 wave verticals, no top or base loading. 2. must be able to standup to new
Thanks for all the responses, too many to reply to individually. I haven't decided yet which way to go for sure, but am leaning toward something like 40-50' of tower with mast 'stinger' out the top.
I use 1/4" EHS guy wire for my trams. The forces on a tram can be huge if you aren't careful. David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://www.k1ttt.net AR-Cluster node: 145.69MHz or
It depends on the angle of the dangle, so to speak. The the copy of the YCCC Scuttlebutt article at the top of the page at: http://www.k1ttt.net/technote/tram.html for calculating forces. In the exam
I rig mine so the rope pulling the antenna up the tower is actually pulling the pulley and the antenna is hanging from the pulley by a separate rope. And on another comment about deadends. At the tow

A ham 4 probably that's been 'brought down to ground level' like that may not be worth $100, especially with no control box (which probably floated away with the house). I would guess that the tree c
Maybe you had the wrong expectations. Beverages (with a capital B) are very inefficient antennas so the signals you receive will always be much weaker on the Beverage than on a typical transmit dipol
Nope. One wire goes and most of the time the whole thing comes down. The imbalance in force is usually enough to pull that layer out of alignment and then the down force from the other guys and the w
Yes, apparently lead is a possibility... though I would expect there may be future environmental concerns when it comes to demolition time. see the 'high density concrete' entry in the table at: http
I prefer the 'close enough' adjustment method. This works for any units and any band. The formula is just length*change/frequency As long as the units of 'change' (how much you want to move the reson
Or just wrap once to insulate and then seal the whole splice in that underwater heatshrink splice sealer stuff. David Robbins K1TTT e-mail: mailto:k1ttt@arrl.net web: http://www.k1ttt.net AR-Cluster
