Anyone with a Bobcat (skidsteer) and a hydraulic post hole auger should be able to screw in anything you would attempt to turn in manually. You'll need some kind of adapter to attach to the eye of th
I used some channel iron with an opening around 3 1/2 inches, just so it enclosed the leg nicely. Way stronger than the original and if you change your mind and want a different tower, you have enoug
Run a slit down the 2IPS40 pipe, compress it to get it in, then it'll expand and will work perfectly.... 73 Don VE6JY _______________________________________________ _________________________________

Pete, I have the DXE RG-5000. Altho I am 60km from the nearest mw transmitters, I have lots of mixing products across the low bands when it is installed, using one of the Wellbrook active loop antenn
The spectrum is clean (using the Perseus SDR) from any mixing products until the RG5000 is put in line. Most of the time, the weak signal lw and mw spectrum is of interest so I don't want to remove o
I've had to do similar with a die grinder and a high speed carbide tool. It really doesn't take all that long compared to, say using a hand file! In my limited experience you want a bit that is quite

Both the small RAU and the RAK will fit in Rohn 25. The RAK is a tight fit but it can be done without having to cut or bend any braces. The taller base adapter is suggested as it will position the mo
If I didn't use the 80m squares and the 160 square as a primary rx antennas, I'd hardly hear anything. Most of the fancy specialized rx antennas just don't capture enough signal to be of much use - n
