81. [Towertalk] which base is recommended? (score: 1)

Zig, You could do what I did and use the pier pin base as well. They'll all work and work fine. Sinking a section in concrete makes the installation work a little easier. With my tower, we assembled

I was a person who was going to do a bracketed tower. The "attractive" part is that Rohn says you can go 30 feet or so above the bracket. In other words, you can put up Rohn 25 at pretty low cost w/n

Sure, but like everything with Rohn, it's not completely clear why you need two brackets. There is no spec given for a single bracket installation. Then the other funny thing in ALL their specs is wh

Jeff, Warning this is long as I didn't know how to better describe things! First of all, I would NOT guy anything to a chimney. Most chimney masonry I have seen is not necessarily all that strong and

Not to nitpick, but I disagree. Concrete cures by a process called hydration. This involves moisture being absorbed into the concrete. That's why it's best to keep concrete covered in plastic for a w

Well Jason, congratulations. As someone who also just put up his first tower, I can say that you will be very happy and pleased! I had to do some major digging in my back yard this summer and rented

RG8 is fine. It's the good ol standby. However, there are many newer cables that have far better performance. Of course, RG8 is very cheap. It's 20 cents a foot cheaper than some of the other stuff.

Cable Xperts sells these and I've used a lot of them. Strip your cable like you would a PL259. Then solder away! Heat the center pin up and then let the solder flow into the hole. Once the center con

Amazing! I wonder how many times a year planes get hit and I wonder what it does to the avionics. I know on a sailboat it can do all sorts of bad things to the instruments. I wonder on a plane, how t

At the same time though, grounding helps to eliminate static buildup on a tower or object. Preventing charge buildup helps prevent strikes. So it does a dual purpose. It does indeed help to ward off

A couple of points: 1.) Filing down the center conductor slightly, helps to prevent any misalignment problems. If the end of the conductor is even slightly bent due to clipping the cable, you will ha

I've not seen this problem ever. I've tie wrapped or taped all my cables over the years and have never seen an issue. It's hard for me to believe a little tie wrap could hurt a dielectric. Even if yo

I understand that. I've never seen it happen with any of the setups that I have done. Maybe I'm just careful about my cable runs. 73, Jon NA9D -- Jon Ogden NA9D (ex: KE9NA) Life Member: ARRL, NRA Mem

Are you asking about grounding or just attaching? For grounding, I've seen pictures of how people have used PL-259 bullets and Andrew grounding kits. For my tower, I decided to use "blitz bugs" or "s

I agree. I had one up and dumped it for an Alpha-Delta multi-band dipole which while very sharp and narrow banded on 80 still is a very good antenna for domestic stations on 80 and 40 at my height of

Not anything like us here. That's one reason why you guys can start runs to Europe a couple hours earlier and keep them going a couple hours longer than us. And yes, it helps to be closer to them by

I'd agree with you Hasan. Also, keep in mind to that the currents and voltages in each leg of a dipole are opposite in both sign and in phase. I've read some literature that suggests you actually get
