A word of warning about using small nylon twine as a pull string. I can saw through plastic and cables. In fact electricians some times use it to saw off PVC pipe. Slightly larger twine is safer. 73
In training from my employer the fall arrest connection was always on the back, and the fall arrest gear we were issued only had the back D ring. Also that is supported by information in a book avail
I have had a problem with SWR on a 6BTV with resonant freq being lower than expected. A friend advised me that sometimes the lower end of the aluminum can around the trap makes a bad connection to th
There a re a couple of other wire label options. 3M and maybe others make wire labels that have a white surface to write info on and a clear portion of tape covers the writing to preserve it. Another
There can be problem with RG-6 compression fittings if not matched to the cable. Some of the wrong size will some times almost fall off. In my work we used them and our shop guy finally made a test j
Hi Bill, The only thing I have heard about stacking tribanders was at W7GG. The had a 3 stack of KT34s and found that a 2 stack would work better for most bands. I don't know any of the details, only

I have used a pixelsat loop off and on for a couple of years. I would recommend it although so far I have not had great success with long distance DX signals on the low bands. It does work better tha
I have used something else to cover the connectors before using tape or coax seal. Plumbers teflon tape is not too expensive and can be tightly wound on the connectors to prevent anything from sticki
It might be possible that the pictures do not accurately show the condition of the towers in question. Could be that they are of uncertain quality/condition, and they want to make sure that they don'
In the Portland,OR area I have one friend who was pressured by the county to pay taxes on his commercial tower when it was only an amateur tower. Apparently in driving by and seeing his antennas made

They recommend retracting the STEPP IR elements so they will not sustain damage if the elements break. That way only the elements would be damaged. I think they actually do pretty well in high winds
I have seen in many years of working with wire that solid conductor can fracture and break a lot more often than stranded conductors. Especially if any kind of nick in the conductor when insulation w
