I wanted to take advantage of this topic being raised to plug my favorite tower safety topic - permanently installed fall protection systems. You can see an example of such a system at http://www.try
The Mag 340N at N6NF went up the tower once, and tuned perfectly that first time. You must, no really - you must, tune each element by the book before assembling the complete antenna. That thing is a
In my limited experience (2 stations with these antennas), the failure point is the black saddle element mounts. They fail (apparently), due to UV exposure. I'd either tape or paint them over, just t
All of the usual suspects carry good antenna wire of various sorts. www.cablexperts.com www.davisrf.com www.thewireman.com GL, **dan, K6IF (VC1R in WPX SSB)
I'm sold on the new 'N' type Force 12 design. It is long - about 85% of full size, but plays well and is _much_ better mechanically than their older designs. You can also make one fairly easily. No b
I think the answer is highly dependent on your station's geography and configuration. A couple of possible answers. 1) For close in, 'domestic' stuff, an inverted V works fine. I use one with its ape
I'm posting this in the probably vain hope that one of you guys has seen this situation before. I know that the 'real' answer is either a) model it on a computer or b) experiment - but maybe I can sh
I am about to install a Butternut HF-2V as my backup antenna for 40 and 80. Primary use is contesting, esp. domestic contesting. I plan to mount the antenna "Team Vertical" style - the base of the an
This true story may help others to avoid trouble in the future. It may also bore you - my apologies in advance :-) About a year ago, we bought a cabin in northern California on a site with a decent t
I bought 30 of the kb-3000 Kwik Blocks. I plan to use 6 of them to mount my 3 second radio vertical dipoles. If you could use any, I've got 24 spares that I will sell for $2/ea. or 10 for $15. You ca
trusses, coax supports, antenna tram lines, etc. I just found an amazingly cheap supplier at http://www.scroungecentral.com/dcable.pdf . Examples: 490' of 1/16" 1x7 galvanized steel cable for $7.35
The 340N is a great antenna. We have one up at N6NF's place, and it plays like a maestro! **dan To: <towertalk@contesting.com> like To: <towertalk@contesting.com> What QTH most To: <towertalk@contest
A couple of thoughts on the Mag 340N interacting with tri-banders: 1) The biggest issue, by far, is the fact that full size 40 meter antennas have a secondary resonance very near (or even in) the 15
Your milage may vary. I am not a tower climbing professional. Steve is really the one to answer this question. Objects in the mirror are closer than they appear. To me, the clothes are dependent on t
Can anyone tell me that inner diameter of the tubing that makes up the element tips of the Hy-Gain 105CA? I know that the outer diameter is .438", but I need the inner diameter. Thanks much! **dan, K
For WPX in March, I am going to need to do very well working Japan on 40 meters. I am located near San Francisco, and for transmit I will have a 3 element F12 yagi @ 75' looking down a 10 degree slop
Can anyone tell me the diameter and thread count of the bolts that grab the mast on a TB-3 thrust bearing? Thanks much! **dan, K6IF AN Wireless Self Supporting Towers are now available! Windloading t
I've asked enough questions and received enough great advice on TT - I wanted to try to contribute something for a change :-) In my recent installation of a Trylon 72' tower, I decided to install a '
In my experience, which I have to admit is limited to the computer screen (!), you have two choices in designing 2-3 element interlaced yagi's for 10/15 meters: 1) Put the 15 meter driven and reflect
Great thread on small lot antennas, I have one data point to add. Back in the day, say 70's and early 80's, Cam Pierce, K6RU (SK), used to do multi-multi out of his 1/4 acre suburban lot. If memory s
