A Cost Effective Current-mode 1:1 Balun
describes a 1:1 balun. Introduction A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors. The balun is formed by winding several turns of coax on the ferrite…
4m Slim Jim Antenna
This 4m Slim Jim is cheap and easy to build yet it greatly out performs the more usual dipole due to its low angle of radiation. An SWR of 1:1 is obtainable across the 4m FM band with simple adjustment. The photograph and PDF diagram show the construction, however a brief description is also given….
Understanding Solar Indices
By Ken Larson, KJ6RZ Long distance HF radio communications is made possible by a region of charged particles in the Earth’s upper atmosphere, 30 to 200 miles above the Earth’s surface. This region is called the ionosphere.
Rewinding Power Transformers: Considerations and Step-by-Step Guide
Transformers are vital in radio projects, often salvaged for reuse. Understanding their power handling, testing methods, and rewinding techniques can enhance your projects while reducing costs significantly. Happy winding!
J-vertical Antenna for 10 meters band
Article by EI9GQ My first J vertical was a Slim Jim for two metres. This simple aerial performed better than a centre fed dipole at the same height. I compared it with an end fed half wave and an end fed 5/8 wave vertical. The Slim Jim always gave better results. SLIM JIM When I…
