Topband: INV L matching

[Tom | SP5XO]

Hello OMs Topbbanders
As I'm planning to put up inverted L antenna for next season i will face
the matching vs bandwidth struggle I know there is a cure for short
vertical section and low impedance (with reasonable radial system) and I
already tested some extended horizontal section and matching capacitor in
the feeedpoint

However i was considering some other impedance matching methods and came
across DK7ZB matching transformers. For example to get good match for 28Ohm
yagi there is 1/4 wave 75Ohm parallel feedlines transformer used with good,
wideband match. Since short vertical inv L over reasonable ground should
have roughly 20 OHm impedance that could work here as well.

 Sure it is 2 x quarter wave 75 OHM coax (shortened by VF) but is there any
wideband "gain" for such feeding method? It would be still easier than
switching remotely some caps each 10kHz or something.

Is there anybody who tried this one?
Thanks
Tom
