Since your budget seems to be unlimited, why not go for the SteppIR 4 element? It is not the best for contesting for probably for everything else. 73 Keith NM5G Thanks guys for your replys! I am curr
Band changes too slow on the SteppIR when checking another band for opening while trying to hold current run freq. Plus, if you have a modern rig with two receivers you can hear both bands at the sam
WD40. You can use a propane or napp torch to heat the bearing. The aluminum will expand more than the steel and possible break the corrosion/rust. 73, Keith NM5G I have a Glen Martin TB-25 Thrust Bea
Put them up any way they will fit together. If you are concerned about how they will look while up, just paint them all to match. If you are concerned about structural integrity, consult an engineer
Using this method one can point their 30 degree aperture multi-element beam with one degree accuracy. :) 73, Keith NM5G --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-b
The 600 in LMR600 represents the outer diameter of the cable, .600 inch. This is really heavy duty cable. I have a couple runs going up my tower. Putting on the special connectors is quite easy. The
What does the manufacturer recommend? Would the 2:1 balun be for 100 ohms rather than 25? I would try to get feed point impedance to 50 ohms then use a standard 1:1 current balun or RF choke. A hairp
The MonstIR has MUCH more gain than the 2el. Couple that with uncertainty about your ground losses and you could easily outperform the little Yagi pointed at any station. 73, Keith NM5G It seems that
I am not familiar with the Optibeam but had a similar problem with my antenna. To make a long story short, one of the loading coils (open air winding) was positioned very close to a bolt used to hold
small tribander do so primarily to reduce cost. I agree with this assessment. Next year a group of us are going to Malta for a week of fun. We debated whether to take an existing tri-bander or obtai
Too old? You are younger than me. Come over sometime and I will show you how to climb my 150 footer. :) 73, Keith NM5G I'm planning a Hazer for my 50' Rohn 25 tower. I'm 62 and like to experiment wit
I would choose a ventilated aluminum enclosure. You can mount bulkhead Polyphasers and attach the box to a tower leg using metal clamps. 73, Keith NM5G Hi all, I am about to erect a 50' Rohn 25 tower
It is usually the gas tube that begins to falter after a number of hits. This results in significant insertion loss. Temporarily replace the unit with a barrel connector to see if there is any improv
I am planning to install a 2 el 80M Yagi. Originally it was going on a 120 foot Rohn 55G tower. I now have some flexibility and can put it on a taller tower, up to 190 feet. What are the recommended
Rick, Thanks to you and many others for the feedback. I am going with 140 feet. This should be a good compromise between domestic and DX operation. I also have an 80M vertical that works quite well b
Looking at my PT-2, the pointer is at 5. The label just under the sliding pointer says "Gauge is calibrated. May not read Zero at rest." 73 Keith NM5G Hello Team, I just picked up my Loos gauge to ch
Why not spend an extra quarter and go first class with a parabolic dish. <grin> 73, Keith NM5G _______________________________________________ _______________________________________________ TowerTal
As recommended by the manufacturer and many others, I use at least 10 feet of steel from anchor point to the Phillystran. Each end is terminated by thimble and big grip, and a bow shackle connects th
I saw a cable guy searching for underground conduit by using a T handle made from hardened steel. Of course, this only works in regular, damp earth. 73, Keith NM5G I'm getting ready to trench in a ca
There was recently a program on PBS (Nova, I think) that reviewed current research on lightning strikes. This research is done mainly in the state of Florida. The potential in a typical thunder cloud
