I agree with John G4ZTR: Don't just hang a messenger wire (what your steel wire is called) onto your tower and load it with coax and control cables without considering the sideways force this will im
There is a program which you can use to estimate the side load on the tower. Look at the following link. http://www.spaceagecontrol.com/calccabl.htm?F=75&a=85&q=0.200044091&g=32.18503937&Submit+Butto
I don't know if HTTA has any arrival angle data for 6M. It's predecessor YTAD did not. Without arrival angle data how would you know some antenna height change is good, bad or indifferent. I seem to
This has been a nightmare. I got a new TH-2 a few months ago. Mounted on the roof at 22'. 10/20M behaved as expected. Tuned for the CW segment. 15M had a high SWR at the low end of the CW band. I tri
I may be wrong but I believe one has to know the complex impedance of the mismatched load before doing anything. This is the real problem as most hams can't measure anything but SWR. There are lots o
Came late to this thread. Running slow, baring mechanical binding usually is caused by defective motor capacitor in control box. Replacing it does wonders. 73 de Brian/K3KO Before you do anything, wh
You might also consider the total coax length of each option. You don't say what frequencies you plan to operate. However if 6M and above an extra 75' might introduce significant extra loss-- dependi
I guess the rest of the earth is flat. With the uneven terrain around here no way pre-cut guys would work. Also there is a likelihood that where you try to screw in an anchor, you can't because of ro
The problem of "towers" walking them selves up from the ground is something the utility companies have a lot of experience. It seems that wind direction changes exert forces on one side and then anot
Guys, I really don't know why these wildly varying multiple lobes is a big surprise. Astronomers have been horizontally "stacking" antennas for more than 50 years. Some of the baselines are as large
Once the discussed towers are measured, it would be interesting to know what the conclusions are. The eye is easily fooled with regards to verticality. Even the Romans knew this. The columns to their
John, I can tell you it cannot handle a 3 element tribander. Way back when my TA-33jr continually stripped its gears. The rotor has no brake. I went through about five sets of gears before getting ri
Guys, I purchased a roll of 3/16" SS wire rope which was clearly labeled 304SS from Home Depot. When I got home, I tested it with a magnet. It was highly attractive. It gets returned. I know there ar
That is the article I used to make my judgement. The reason that "magnetism matters": It is the only method at my disposal to determine real SS from fake. I simply distrust anything made in China as
I lost one trap due to exactly this. Wood wasp got into the trap and built his mud and saliva nest. I've taken a bit different route. I use fine mesh plastic window screen. The reasoning of course is
Yes, if it conducts it will radiate. This is the put up the any old thing philosophy. However, experimentation is expensive and time consuming and has the possibility of hobbling ones signal. That ca
Have had some trouble with intermittent traps and water in the traps. Look at E-HAM reviews, others have too. The water in the traps appears to come from the "downhill" trap covers not keeping water
Shawn, You say the tower is an EZWAY. Do you mean the two or three section crankup tower with the wonder ground post? I had three of them over a 10 year period in the 60's. If you do: 1) The tower is
I recently had an internet wireless antenna/unit installed as our DSL was painfully slow. Now I notice RFI in the AM broadcast band and into the 160 meter band. There may more RFI issues on other ban
I've ordered and received the replacement cable from Tashjian the cables for my lm470. Only problem is my lm470 cable was one long piece whereas the ones Tashjian sent are multiple pieces for each se
