Fan-Dipoles for the Shortwave Ba
Heres a neat 1:1 50 ohm balun for use on HF horizontal wire dipoles. It uses an AM radio ferrite rod, with 3x14 turns of wire. 10-14 turns should be good for 2-30MHz. I used 18SWG enammeled copper wire. It all fits in a small project box. Great for setting up portable.
The frequency of extreme rain means parts of the state simply can’t absorb more water. Here’s how it happens.
I know we would be getting pretty large size-wise but have you ever done a JE Labs style baffle in width but tall enough for two vertical 15" woofers with...
John Janks furthers his experimental evidence for the efficacy of dowsing rods (dipoles).

Another common place one can see dipoles is as antennas for the FM band - these are folded dipoles. The tips of the antenna are folded back until they

STIKER MObil ” Bila yang memakai stiker glossy perawatannya seperti mobil umum. Stiker ini dapat dapat dipoles, lho bro ” ungkap Bro Imam.
Vertical H TX antenna with no ground system. Capacity hatted off-centre fed vertical dipoles. Homebrew K9AY low noise directional loop array
I understand the discussion is about open baffle and not necessarily dipoles exactly, but I'm wondering if using felt effects the radiation reaching the...
Jika teman - teman mempunyai macbook pro jadul dan kondisinya lecek, banyak baret, atau dent dibeberapa tempat. Jangan berkecil hati semua itu bisa dipoles d...
The Maypole HF multiband antenna. Build this Maypole style antenna from this article. Get on many ham bands with one feed line and multiple dipoles!
A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables. Many hams connect the center conductor of the co...
This question regards Ewing's molecular theory of magnetism. I.) Ewing's molecular theory of magnetism describes every magnetic substance as being a collection of dipoles that are initially in a st...
Is KrF2 polar or nonpolar? The Kr-F bond is polar, but the linear and symmetrical shape of the molecule makes it nonpolar as the bond dipoles cancel each other out.
