vhf dummy load

20m mini loaded dipole - It is very simple to build and you can tune it in your shack room

Magic T combiners splitters - The magic "T" combiner is a very useful device. It can provide equal voltages, equal current, or equal power to matched or unmatched loads. It is not a magic bullet.

Ladder line J-Pole - Building a VHF or UHF Ladder Line J-Pole Antenna

Loading inductors in mobile antennas - Mobile antennas, loading coil current, and loaded antennas. efficiency and electrical rules. Loading inductors used in mobile HF antennas.

Assembly of the Lightningbolt Quad - One of the best antenna values on the market is the LightningBolt Quad. At about half the cost of a tri-band yagi, you get five band coverage with a single coax feedline and excellent performance from a light, low wind load antenna.

Shrunken Quad - VHF quad antenna for transmitter hunting.

Optimizing Inductors - While intended mainly for antenna loading coils, this article also applies to other resonant systems, such as amplifier tank circuits.

ARIDX by UA1AAF - At the moment the most used program is UA1AAF. It is an excellent program written by Boris, UA1AAF, to handle ARI International DX Contest. It can simulate K1EA or N6TR workings; it will be possible to connect the RTX to the computer using a standard interface in such a way as to transmit directly in CW from the keyboard; most of the controls are like K1EA's CT and N6TR's TR ; on line help provides almost all the information necessary for using the program. Is possible to insert QSO after the contest. An appropriate utility in included for conversion in ADIF format. The program is very small and therefore works without any problems on any IBM compatible computer with DOS 3.3 and over or Windows 95/98.

The VHF Dxpedition to Dominica - Main goals of this dx pedition was test out a MID SIZE 2MXP20 dual polarity or cross polarized Yagis in a field environment and shoot for a record number of EME QSO's using this system

Rotating Tower Systems - Using our components you can build a rotating tower with greater capability than 3-4 static towers. A rotating tower allows common rotation of HF stacked arrays, VHF and UHF arrays, and antennas mounted at optimum heights. Component design also allows tower shunt loading and end support for wire antennas

Alpha Linear Amplifiers  ^pop - RF Concepts manufacturer of Alpha Linear Amplifiers, amateur radio RF power amplifiers, commercial power amplifiers, power meters and dummy loads.

Low cost frequency stabilisation - The Icom IC-746 is quite a popular HF/VHF multimode transceiver which has one shortcoming in its standard configuration when used to operate modes requiring good medium-term frequency stability.

FT-817, FT-847, FT-857, FT-857D, FT-897 and FT-897D Memory Cloning - The complete status of the FT-817, FT-847, FT-857, FT-857D, FT-897 or FT-897D memories can be read into the computer and saved to disk. Any saved file can be subsequently reloaded into the computer and sent back to the rig. This facility uses these rig's ability to clone configurations from one rig to another using the serial port.
