To each his own. There are things that scare me, but climbing a well engineered tower is not one. I go up several times a season just to shoot a scenic panorama while standing on the tower top plate

When you say power lines, do you mean transmissions lines, or the 220 drop into the buildings? Big difference. If you are talking transmission lines, many states have laws against that. Plus if the

I've thought of putting up a tower cam, but modifying a cam corder. I managed to pick up a digital one on close out. 20:1 mechanical zoom. I hope to use pan, tilt, and zoom controls, but it's going t

Keep watch at Best Buy, Circuit City, and the other big discount stores. They often have very good prices on the demonstrators that are hooked up for people to play with. (watch out for sticky finge

Something to remember about the BX through the HDBX series. They are made from fat stamped steel and like aircraft structures derive their strength from the shape of the stamped material. Anything t

<snip> HDBX48 metal on one leg! This caused the tower to actually fold over at the 6ft level, right where the new rotor plate was mounted! Had I mounted right at ground level, there is a chance, I gu

How about a rose trellis? That's not a joke. IE stick with a good anti climb fence which will work just fine as a trellis. Kids aren't going to mess with a rose bush, and even if they did the fence i

I would think the fence serving as a trellis or with the lattice covering the fence would be acceptable...except for the climate<:-)) You have the fence and it is camoflaged. Getting creative, you c

I'm thinking along the lines of camoflaging a fence instead of trying to jury rig anti-climb panels. I no longer remember the name of the stuff, but wayyy back when I lived on a farm (and even farmed

A hint for reusing self tapping bolts without reaming out the hole. When reinserting self tapping bolts, apply a light pressure and *slowly* turn them the wrong way (as if you were unscrewing them).

Wait a minute: It's been a long time since I had one let alone taking it apart, but... I thought there were 5 or 6 1/4-20 screws around the outside edge of the rotor holding the retaining ring on. Ma

I think it's more a matter of availability. I could only get basic DSL at 128K, or 256K. It cost $96 a month for 128K while 256K was double that. That was just for the phone line. A dedicated IP at

We, or most of us, do use rebar, but it is used to reinforce the concrete and the ROHN catalog has instructions on how to arrange (lengths and bends to make) the rebar. I'm a firm believer that they

Or it could be a Cushcraft ATB-34. How is the driven element attached to the boom? If it fits into a cylindrical phenolic insulator it is *probably* the ATB34. They normally used a balum but direct c
