Wonder Whip Antenna
A £10 QRP Portable Multiband Antenna for HF, VHF and UHF
Florence RadioFest 2019
on Saturday 25 May 2019 i will take part to the upcoming Florence RadioFest as organizer. The Florence RadioFest is a local amateur radio HamFest managed by the members of the ARI Section of Florence. We expect to have over 50 private amateur radio oeprators and more than 10 amateur radio business companies represented.
Quarter Wave Vertical Antennas
One of the most useful antennas in the repertoire is the Marconi or quarter wave grounded vertical antenna. Its invention made it possible to halve the length of antennas, simplifying communications, especially at HF and below.
Long Waves, Short Antennas
designing for MF and LF communications When radio began, it started with low frequency communications, which it was thought was the answer to long distance communications. Since then we have seen the development of sky wave communications on HF frequencies, followed by the proliferation of communications system using the VHF and UHF direct wave and…
Feeder Radiation
When you connect centre fed antennas, like dipoles, Vs, triangles, yagis, rhombics, loops and so on, to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation.

Using Solar Power and 12 Volt Batteries
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…
