Simple HF Baluns for 50/75 ohm coax
- Show diagrams, winding methods and tables of some 1:1 and 4:1 baluns for 1.8 - 30 MHz suitable for use up to 200W (400W peak) on systems using 50 or 75 ohm coaxial cable input where SWR should not exceed 1.6:1.
Sloping Vee 470
- Article describes the design and simulation of a multiband Sloping Vee antenna for the HF band, using the software MMANA-GAL. Design with 470 ohms resistive loads. The antenna requires a 4:1 balun.
SWL antenna distribution system
- A methodology for connecting multiple LF/MF/HF receivers to a single antenna via readily available and inexpensive 75-ohm TV cable. Custom made baluns and splitters provide impedance matching and prevent interaction between receivers.
Windom Antenna with 4:1 balun
- The Windom is an Off-center wire multiband Antenna. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers .
