The 1/4 ground plane might be just the ticket. If you are just starting out in amateur radio, you may not have collected the amount of resources that a more seasoned ham might have. I have a length of 12 gauge solid copper wire that I've stripped the insulation off. I'll be using this for the antenna elements.

1/2 Wavelength Dipole: Length L (feet) = 468/f (MHz). Length L (meters) = 142.5/f (MHz). Add 4.7 percent to L for an Inverted V configuration, depending on apex angle. The antenna height (H) above terrain should be 20 feet minimum.

Aug 01, 2010 · [A] HF radio The radio is the core of your station. You will need a transceiver, a radio that can both send (transmit) and receive on the amateur radio bands. A 100 Watt, multi-mode, multi-band radio is a good choice for most operators.

Longwires, random wires, inverted L's, true Windom antennas, or any other single wire "feeder" or antenna require a desk RF ground connection. When such antennas or feed lines are brought into the shack, they also bring grounding problems to the operating area.

Conveniently determine the diameter, in inches or millimeters, of wire gauges from 10 to 38 gauge.
Inventor Hawkes makes a VHF/UHF version of his antenna for use from 50 to 800 megahertz. It can be used for VHF/UHF TV reception, and for transmission /reception on the six and two meter, 220, & 440 megahertz Amateur radio bands. It is @14 inches in diameter and is enclosed in a rigid plastic disk, with external mounted F-plug type jack.
3. Measuring HF antenna properties ( H-V pattern , directivity, radiation efficiency, polarisation, etc... is a very big challenge for a ham radio operator. 4. Even if you install the best state of the art HF antenna at 200 ft above ground, made with gold or silver wire and pure diamonds as insulators.... if the propagation is bad ....
The antenna is fed by low loss coax into a 9:1 UnUn. One terminal of the UnUn is connected to a good ground and the other to the antenna wire. The UnUn is located away from the house. Low loss coax is used due to the distance between the radio and the UnUn. Grounding. I used a length of copper water pipe as the earth spike.
