"Does the resistor give these antennas their front to back? If I took out
or bypassed the resistor, would that give me signals off the back? I'm
curious as I don't have room on this lot to make up 4 flags, etc."
Yes, the resistor is what makes the antenna unidirectional , among other
If you short out the resistor, at 1.83 mHz the pattern will be slightly
oval in shape, with zero front-to-back and about 3.5 dB down off the
sides and the feedpoint Z will be about 2.7 - j1725 ohms.
If you open the resistor, at 1.83 mHz the pattern will be perfectly
circular and the feedpoint Z will be about 1.0 + j520 ohms.
"I really like this flag however I'd like to get it as high as I can.
Maybe it's supposed to be close to the ground but that idea is even worse
as I don't have the room."
Putting it up higher buys you hardly anything, really.
