The Sun Can Power Your Ham Station and a Whole Lot More! Solar power or specifically, solar photovoltaic (PV) panels, have become increasingly available as a power source. Solar PV is ideal for powering Amateur radio equipment because PV panels are almost always designed to charge 12 volt battery systems. Coincidently, most Amateur radio equipment…
Magnetic Longwire Baluns
Do these things do exactly what they say they do – or are they total hogwash? Have you seen the ads? This device will match your long wire to your receivers 50 ohm input? Firstly a long wire on HF would be on 28 MHz longer than 120 foot and on the lower bands it just…
160m Antenna – Inverted L
Another antenna added from the antenna plan is a 160 meter ¼ wavelength inverted L. A 130 foot length of 12 gauge PVC covered stranded wire slopes up from the ground system to the 40 foot level of the 45 foot tall fiberglass flagpole (about 60 feet of wire length) and then proceeds about 70…
Vertical Dipole Antenna
VERTICAL DIPOLE Since I had purchased the Kenwood TS-590 transceiver a few months before I got my license, I needed an antenna (or antennas) right away for listening on the ham bands. The antenna that I put up first was a vertical dipole for 10, 15, 20 and 40 meters. The reasons for this selection…
The gamma match
The Gamma match is the most used matching device used for yagi beams. What it does is: A Yagi almost never has an impedance of 50 ohms. In other chapters i told that Gain, bandwith, F/B etc. all relate to eachother these figures are never all high at one point. A well designed yagi has…

2m crossed yagi antenna
This 2m yagi uses design data from DK72B’s excellent yagi website. The element to boom mounting used here may be of use to some as it does not use any polamid mounting / insulating clamps at a cost of 2 euro each ( this is a 7 el crossed Yagi so twelve clamps would be…
