This thread has taken on a creative bent. 1) You wouldn't need a 100w lightbulb in the 5 gallon weather protective cover. 5 or 10 watts would more than do it. And yes, you would want to make sure it
Ideal system: N2RM's design-- Stacked monobanders 40-10 on 120' towers, with single monobanders for each band @ 70' for South or closer-in work. Phased verticals on 80 & 160. Multiple beverages. Midr
Very interesting discussion. When I put my lightning bolt quad up, I was concerned with their system of simply tying all loops together at a common feedpoint. I went so far as to talk with Cebik abou
regarding the tilted foundation: Back in my broadcast days, we were putting a new station on the air. We had four 210' rohn 55 towers, in line, on a river bottom pasture. A hurricane hit, just before
First of all, the you tube link is absolute drivel. Second of all, the ham-legal reflector is the place to have an adult discussion about antenna ordinances, not here. Third of all, even the National
OK, I have been privately chastened for my big mouth on this topic. If I hurt anyone's feelings, I apologize. That wasn't the intent. Let me suggest that if you're serious about fighting what is obvi
And now, for the rest of the story... OK, I was cranky about the repeated posts concerning the you-tube video and the Palmdale CA antenna ordinance. I advocated serious professional work, rather than
Language is a wonderful thing. a) I didn't apologize. b) I didn't retract my comments. c) a little crow, properly seasoned, never hurt anyone. I WAS cranky in my first post, even though the point was
I know this is an age old question. What is your best recommendation on getting some ropes in the tops of my 80 - 100 FT (25 - 33 M) pine trees ? I have heard a sling shot or bow and arrow can work.
Robert, The tennis ball system has an added advantage. It isn't considered a weapon. In some jurisdictions, shooting an arrow or firing a slingshot is considered the same as illegal discharge of a fi
I think you'll find that vertical angle distribution of the two antennas is the major factor, with terrain being the obvious uncontrollable issue. 90' is not a particularly good height for a 40m yagi
I wasn't closely following this thread, and the last post doesn't have the original poster's details...or this would be off-reflector. Don't discount the possibility that the intermod is coming from
I do have one additional "question of the day" and that is if you have had any experience in installing a tailtwister rotator near ground level by running a mast from the top of a Rohn 25 tower about
Nope. W3GM's rotors were mounted on an accessory shelf at 3 or 4' above ground, to make for easy working height. The yagi was up for well over 15 years, with no problems on the tower, and only a few

Pete, Haven't spoken with Ben or his wife since last year, June, so I don't know contemporary information. However, Ben has a day job, which requires travel. His wife was answering the phone, when he

Cell sites are nothing. An AM array proof of performance has 20 radials, with 10 readings each... out to a distance of 8-10 miles. Lot of labor involved. and that was a lifetime ago... labor isn't an
not what I meant, Don. The tower is substantial. Whatever 'proof' was performed was minimal, if they only charged you $1200: It really depends on the nature of the AM array. If it were an omni situat
