January 18th Build Session
January 18 @ 6:00 pm - 9:00 pm
‘Traps” How they work and how to take measurements as you construct one. The first build session on the 18th of January will start with a video presentation concerning trap design for antennas. Then there will be a live demonstration of how to measure a trap while designing one for use in an antenna system.
By using tuned circuits (traps) of appropriate design strategically placed in a dipole, the antenna can be made to show what is essentially fundamental resonance at a number of different frequencies. 10.2 Trap Antennas, The ARRL Antenna Book
Traps are easy to “home-brew” and are effective in a variety of wire antennas for HF use.
