Carefully inspect the PVC element insulators where the elements clamp to the boom. I believe they are made of PVC, and with age and UV exposure, could have cracked when the lifting cable snapped. It'

The effect on the pattern can be significant on VHF. That's why FM broadcast stations generally use fiberglass on the first 20 feet of any guys near the radiating "bays". Ron N6AHA -- FAQ on WWW: htt

Using a transit is probably the best way to determine tower plum. I was a professional team from Sacramento do that on a 100' commercial tower I had installed for broadcast use. Buying one may be out

I would worry that the current that flows through the conductor leading to the bottom of the foundation could cause sufficient heat, even though only for a fraction of a second, that the base could f

I put up a 555 in a very windy location several years ago, and I would not recommend trying to install a new bolt in the existing foundation. The stress on the bolt in the wind is enormous, and even

I read an earlier reply to your post, and must agree that if there are CC&R or zoning restrictions against your tower, you can get in serious trouble if someone "rats you out" for building the tower

I used to live a few miles from that site, and it was awesome to look at! The other station on Oahu was Lualualei on the Waianai coast. As I recall, it was two 1,000' verticals and it's own salt lak

Excuse me, but I seem to get the jist that the $1,200,000 award was just 10% of the property value. It's hard to imagine anybody with a $12 million dollar home that didn't get it by "big corperate pr

I found the same thing with my C-4, so it's not my imagination after all! On 17 meters, the most forward gain is off the back of the beam. 12 meters works the right way and I have worked though a fai

I couldn't find any reference to the C-4's pattern being reversed on 17 meters in the manual (1994 version dwC31.002) or on the web page. Where did you see that information? Ron, N6AHA --Original Mes

Well, there it is, in black and white! I guess my old manual was not detailed enough, but I figured it out on my own. The 15 meter reflector acts like a director on 17, but the front-to-back isn't re

My guess is that it is part of the spreader in the linear loading system. I haven't been up on the roof to see mine in a couple of years, but the part does sound familiar, and I vaguely remember it h

Has anyone come up with a way to add 12 meters to a Force 12 C-4 without severely impacting performance on other bands? The SWR is quite high on 12, and even a rotatable dipole would probably work be

You could be right, Ben. I also worked the ZL9 in 12, and most of the other Pacific DXpeditions. What worries me is that a 5.2:1 SWR in the shack at the end of 100' of RG-213 indicates a 15:1 SWR at
