Topband: W1BB-Style Extended Inverted "L"

[Edward Swynar]

Has anyone ever validated, via computer modelling, Stew Perry's claim that 165' - to 175' was the "optimal" length for a series-tuned (variable capacitor) extended inverted "L"...?

I like the convenience of being able to resonate my "L's" by way of base-mounted air variable capacitors, and am curious if I could still take advantage of this feature, were I to reduce the present overall lengths of 170' per "L", to something like 140', or so, which is still longer than the prescribed 130' for a "normal" 1/4-wave on 1.800-MHz...
