This is post 2389 in a continuing series of simple ham radio antennas.
Here's an interesting antenna "coupler" ("tuner") idea from Australian radio amateur Peter Parker (VK3YE).
According to Peter, this basic L-"tuner" doesn't require a variable capacitor.
Here are some of Peter's comments:
Variable capacitors can sometimes be hard to find. Especially during this time of lockdown with all hamfests cancelled. Described is a 1.8 to 18 MHz L-match antenna coupler that uses double sided fibreglass printed circuit board as a substitute.
