Antenna Matching Coil Adjustment Procedure
This article describes a specific procedure to adjust a shunt matching coil to assure that the input SWR will remain relatively low
Construction de Trappes
In search of a software for the hatches: Coaxial-traps. Why also coaxial hatches? I chose this system, because not having 1.5 mm² copper wires to use, I had however a lot of cable 75 ohm coaxial for CCTV
Low-loss wire traps
Wire traps do exhibit a high Q-factor so are in theory less lossy compared to coax traps, but are NOT SUITED for high power 200w
