4 element yagi for 24MHzPriority listing
- Optimised with the very latest PSO (particle Swarm Optimisation) techniques. Perfect flat SWR and excellent performance throughout the band and easy to self-build.
4m Slim Jim Antenna
- This 4m Slim Jim Antenna 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 ham radio FM band with a simple adjustment.
Digital SWR Power Meter project
- A PIC16F876 based, automatic 1.8 – 60 MHz Digital SWR/WATTmeter capable of displaying both the SWR and P.E.P.power values, with a bar graph on the second line tracking the instantaneous power.
