[TowerTalk] 4 element Delta Loop for 10m

[IZ4EFN Alessio]

Hi guys,

we just bought a 11m delta loop in quite good condition.

The antenna is really perfect: no corrosion, no missing part, clean
elements.

Our intent is to convert it to a 10m delta loop.

Well, we are back from some experience with a 20m 3 element delta loop,
completely homebrewed with the help of some local books, but we had to
completely change the book calculations to have something similar to an
antenna.

Maybe the mathematical approach of these books is quite different from the
phisical world.

We are now designing the new one for 10m (4 elements this time) with these
equations, but would check these with some other measures.

Anyone has ever built a 4 element delta loop for 10m?

Some design advice or complete measurements for "dupe check" would be
appreciated.

Thanks a lot,

Alessio, IZ4EFN (IO4T).
