I prefer pi-net tuners - two variable caps to ground and a variable coil in series in the middle. Easy to build and is a low-pass filter to boot. -- 73, Cecil, W5DXP Hi Cecil Hi "Matthew&Wendy" I prefer resonant antennas and transmission lines that match them. You just can't beat a resonant antenna for radiation. Tuners squander AT BEST 1 or 2 db. At WORST (as Cecil has posted here regarding "shootouts") 10 db. So build your antenna resonant, match it, and don't bother with a tuner. If impedance transformation is necessary, use a transformer; That's why they're called transformers. That's what they're for. Just my 2 cents. 73 H. NQ5H PS Wire antennas are CHEAP. |
