"John S" wrote in message ... snip I'll comment, just to see if I'm envisioning his configuration properly. If a folded dipole is constructed, the feedpoint impedance can be increased by adding another parallel wire, forming a 3 wire folded dipole. A 5 wire paralleled folded dipole would have an even higher feedpoint impedance. So if I envision the configuration correctly, half of a 5 wire folded dipole is used to construct a 5 wire folded vertical monopole. The antenna is then shortened (but resonated) by putting a loading coil in each of the 5 wires. Yep, that's it. Total coil losses are lower because only 1/5 of the current flows through each, giving each a resistance loss of (1/5*I)^2*R. Is that it? I would have to go back to the model to see the relation of the central current to the current in the four legs. -- Jim Pennino |
