My Radio Room is located in the second bedroom of our house. In there you will find two stations setup. The main station consists of a Yaesu FT-2000 connected to a power amplifier that allows my transmitted signal to have a power rating of one Kilowatt. I also have three rotors that allow my antennas to rotate 360 degrees so that I may point the antenna that the rotor controls in the direction of any station. There’s also 2 antenna switches that control which antenna I wish to use and a digital interface that allows the computer to work with the transceiver so that I can operate the various digital modes.
The second station is setup as an auxiliary station to use when I need a break from my computer work. It consists of an Icom IC-9100 and it shares one of the rotors from the main station. There’s also a digital interface for performing digital communications.
Antennas are an important part of radio signal transmission and reception. Over the past 5 years I’ve built or assembled several antennas, either commercially bought or scratch built. The reason for having so many antennas is that they are specific for certain frequencies. Here’s a list of my antennas with the frequencies they cover.
- Force 12 Delta 4SXL yagi. Covers 7, 14, 21 and the 28 MHZ (Megahertz).
- Cubex 3 element 5 band Quad. Covers 14, 18, 21, 24 and 28 MHz.
- Gap Voyager IV. Covers 1.8, 3.5, 7, 14 MHz.
- Cushcraft D3 Rotatable Dipole. Covers 10 MHz
- Cubex 6n2 Quad. Covers 50 and 144 MHz.
- Multi-band Inverted Vee. Covers 1.8, 3.5, 10 MHz scratch built.
An integral part of an antenna is the way it’s supported in the air. Where my antennas are located there are no trees so I must rely on towers to support these antennas. I have 3 towers.
- US Towers HDX- 572. Has a maximum height of 72 feet and is adjustable in height.
- US Towers TMM-541SS. Has a maximum height of 41 feet and is adjustable in height.
- Rohn 25. Has a fixed height of 40 feet.
