..."I've never heard of electrician's putty. Is it something that the brain-fried clerks in HD could point me to? "... Nope, tried that, but a good clerk will know about it. I think the stuff your ar
I don't think I would take the antenna down unless you are at the point of shipping the whole thing back to FM for a refund. I can't think of any possible problem with the antenna that could cause th
Darn, I can't believe I forgot to Google. The part number for my supply is PSU66C-8 http://www.powerbox.se/pdf/catalogues/external.pdf This document has a PSU66C-8 listed but the C designator (or A o
I'm sure that has been done, but the results of that doesn't make a good news story. _______________________________________________ _______________________________________________ TowerTalk mailing
If the trees are so close that it turns vertically but not horizontally, that will only last about 3 months, then he won't be able to turn it mounted vertically. Besides if the antenna is very low, m
-- Well, my original statement is not 100% true for all heights, and neither is yours. Here are some EZNEC numbers for a three element Yagi turned either vertically of horizontally. Height ___ Horz A
Ground losses for both antennas were included to the extent that EZNEC Sommerfield-Norton ground is accurate. At the heights used in these examples, that should be a good estimate. What is "real worl
You are correct, Ward. That info is only part of the whole story. Clearly as can be seen in my previous chart, the vertical has a lower take-off angle, but it is not clear how the gains compare at so
Could be really interesting for the swimmers. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://li
Glad to hear you now have a working antenna Bill. From your new information, I would conclude that my speculation was correct, a power supply problem. It is possible that there may also be a motor pr
I thought this was an interesting question, but no one tackled it except for one guy who said that's the way it's done. So is that really the reason? _______________________________________________ _
From your "loose cable on the reel" comment I'm assuming you don't have the positive pull-down configuration. After you crank the tower "up" 4 ft, while the tower is horizontal, it won't crank by dow
Taping the coax to the mast is almost a necessity with a crank-up, especially when there is an antenna is mounted just above the top of the tower. The tower tie point would have to be at the top of t
"They purposely built a 5/8 wavelength radiator design in order to suppress higher lobe radiation causing selective fading at a particular radius from the antenna. " Actually WSM started out with som
Here is a trick you can do to make a 40 meter dipole be resonant on 15 meters at the frequency you want it to be. First build a 40 meter dipole, about 68 ft. Then at 7 ft either side of the center, a
K8RI's assessment of the grounding problem is right on. I would like to add a few comments. Current waveforms for lightning simulation is not always the same. Different waveforms are used for differe
True, and you are not going to melt this. And your numbers look close. If it is 1/64 thick, then each of these lines would have just slightly less copper than a #00 wire, and lower skin resistance. D
I has a little more gain in the direction directly opposite the direction the top wire is running away from the vertical wire (maybe 2 dB or so). The angle created by bending a wire causes some field

A wire on the ground gets tuned to a lower frequency by being on the ground, so to act like a reflector (and tuned to a lower frequency) it has to be shorter than a half wave dipole. You only get a b
