3 WIRE ANTENNA ROTATOR SCHEMATIC
Low Freq. Antennas - techlib
Antennas . Home-made antennas can greatly improve the performance of AM and FM radios, short-wave receivers, and scanners. If you are a talk-radio fan then experiment with the AM band antennas and you will be able to hear shows from all over the country with surprising clarity.
5 Band Cubical Quad - VE3SQB
A number of these quads have been built, using these formulae, with slight variations in wire diameter, but always using bare hard drawn copper wire have delivered the goods with no adjustment of element size, giving good gain, f/b, and bandwidth. I emphasize once more, that if you use insulated wire, or bare copper, different to what I have used, The above measurements will not be correct.
Arduino Rotator Computer Interface and Controller – Radio
Updated 2018-02-01 Introduction This is an Arduino-based rotator interface that interfaces a computer to a rotator or rotator controller, emulating the Yaesu GS-232A/B and Easycom protocols which are supported by a myriad of logging, contest, and control programs. It can be easily interfaced with commercial rotator control units. With the addition of a proper capacity

Noot: This antenna is not being used anymore and replaced by a LZ1AQ crossed loop receive antenna. Please check the article on my website (link). Living in a nice neighborhood with neighbors is mostly very fine but mostly not when you are a ham operator.

CB co-phased antennas | WorldwideDX Radio Forum
Jan 15, 2015with a single antenna you want to use 50 ohm coax . co-phase use 70-72 ohm coax. if your mounting the radio above behind rear view mirror , then run coax above headliner and down rear c-pillars and out through vent holes behind rear seat panel as it will work with plenty of excess coaxial >
links. 50 mhz: amateur radio direction finding: amiga: antenner etc. antique radio, museum etc

Electronic Projects mostly associated with solar power. With these requirements in mind, and some others, I decided on a variation of National Semiconductors "Micro Wire"(TM).
