Nutty Antenna Idea -- Complete with Rhetorical Questions

I see there is no reason it shouldn't work once he gets them tuned. How much would it weigh? That part hadn't occurred to me. Come to think of it, I don't think they were designed to withstand horizontal positioning, but then I don't know the antennas. Anyway, good luck in the antenna. Maybe a vertical dipole? -- 73 for now Buck, N4PGW www.lumpuckeroo.com |

Nutty Antenna Idea -- Complete with Rhetorical Questions
I've done it with pairs of identical "hamsticks" ....
two feet above the cab of my pickup. It made a GREAT NVIS HF antenna! Thanks. I don't own any of them, yet, but it sounds like a possibility. I'm probably going to want DX, though, so NVIS isn't something that I'm seeking. If I'm horizontal, I'll want some elevation. The NVIS was not caused by the hamsticks, themselves, but by their being VERY LOW! (2 feet above my pickup cab is only 8-9 feet high) I'm not in any way claiming hamsticks are the "best" antenna, but if you elevated a dipole made of them, I'm sure they would not act like cloud-burners anymore. -- --Myron A.

Nutty Antenna Idea -- Complete with Rhetorical Questions

Obviously they're intended to be mounted vertically above a ground. What happens if I mount them horizontally, base-to base? If I feed one with coax as designed, would it see the other one as a counterpoise? Could I remove any base matching components and feed them both with a 1:1 balun, in effect duplicating the function of a horizontal wire trap dipole? Will water drain from the traps in their new configuration? Owen Probably not, unless I do something special, like custom drain holes. Being in Southern California, we have a six-month virtually rain-free summer coming up, so I suppose it cold be a fair-weather project. (What do you bet I forget to take it down in October?) |

Anyway, good luck in the antenna. Maybe a vertical dipole? withstand horizontal positioning If I do this, I will have the thing laying on the roof, at or near the peak, so support won't be a consideration. (The far end of each unit could stick out and be self-supporting.) Having it slide down the roof is a bigger worry. vertical dipole Ahah! I started out with a 10m vertical dipole as my first-ever HF antenna, last month. (It has since morphed into an OCF horizontal dipole that I've stretched all the way to 40m with a homebrew pi-network tuner I acquired at the swap meet.). To the point, two opposing trap verticals as a single dipole would be a 70 foot vertical structure and is not within my capabilities. (I would love to try it, though.) "Sal" (KD6VKW) |
