No. And since we're not subject to C&Rs here, even if there was there wouldn't be much they could do. |
That offset dipole - also called a Zep - is featured in a Reading PA WWII airfield and encampment reenactment. In WWII, the offsett dipoles used a ladder line - 600 ohm impedance - where the ground wire did not attach to the antenna.
I was never familiar with Zep antennas. In the Canadian camp, a ham had an interesting setup using principles common in WWII. He explained the concept of tuning antenna impedance by moving the offset. It just never occurred to me that impedance could be tuned by simply shifting the offset. Also interesting his how he support the antenna so high using interconnected fiberglass poles (similar to what is now used on tents) AND adjust zep offset from the ground.
Show is soon; the first weekend of June. It had many ham operators using WWII style techniques and equipment - and lots of old guns and planes.
Some are using flagpoles as a support for the dipole that will not 'offend' neighbors. However, I always thought a J antenna inside a fiberglass flagpole would be a rather interesting way of doing an omnidirectional antenna discretely. Have never seen one. But then they would be discrete.
Satellite as in communication via amateur satellites on 145 and 435 Mhz, or just Geosynchronous conventional satellite receiever?
