I hadn't seen this original post before I replied late on in the thread so I have a couple of additional comments. Although I recommended the Pro Sis Tel series in the other post, if you are only tur

I've done something similar to what Larry has done; however, I use heavy duty, flexible vinyl and fold it into a simple cone. I wrap the top of the cone around the mast above the thrust bearing so it

Depending on the circuits a single GFI outlet at the beginning of the run will serve the entire line. That is what they did in my shop. I can actually short out one of the outlets to ground with bare

If I'm going to install a tower, I really don't have to know anything about the engineering of a tower. It helps, but it's not necessary. I do have to know who does know, or how to find who knows. I

Ahhh... If I take out the quotes there's nothing left in the previous post. Then again if there was any thing other than straight text I don't see it any way. Any post other than text shows up as a b

I still like the good old water drill. It's cheap and easy to use. http://www.rogerhalstead.com/ham_files/ground.htm I've posted it before, but I think it's germane to this discussion. It works well

I'm hoping that history has added the subject of shack wiring, both RF and AC, to the range for Towertalk -- if others disagree, I apologize. My entire shack is on a single 110V circuit (separate 220

It depends on how computer savvy you (or your friends)are, but using an audio interface you should be able to handle the transceiver just fine. There are rotor control boxes that interface with the c

Aluminum is about the only thing that the power company uses nowadays for the drop cable to your house. But you do not want any aluminum inside the house. Most places do not allow its installation an

Nice pictures Roger. Only problem with your installation method is you do not have as good a ground connection with earth as you would if they were driven in. Not at all. That's an old wive's tale. A

I read you already have a different method in mind, but I used to do DFing as part of my job. The loop antenna was several turns of insulated wire inside a copper tube with a tuning cap at the base.

It may depend on where you live, but in this area of Michigan you do not have a choice. Well, you could ignore the codes and not get a building permit, but there are some stiff fines if caught with t

Trying to remember my theory... It's been a long time. I hope this makes a little sense. I think of lightning as a poor square wave. It has an fairly abrupt rise time and a bit slower fall time as I

Presumably there are mechanical differences in hardware, etc., but what I'm really looking for is any noticeable "power sucking loads" that are inherent in the design (sure, our vertical has a 2:1 SW
