Second test this time outdoors, free field, not bad at all.
A small adjustment on 1296 MHz would not be refused but i think it probably take me so long time to do the adjustment.

First measure of the Tonna 55 elem. 1.3GHz.
Perfect VSWR on ~1290 MHz, if the weather is nice I dismantle the antenna to redo the measurements outdoors in a free field.

Today, I am testing an antenna that I have just found in my attic, a gigantic Tonna 55 elements 1.3GHz 23cm! 😮🤪🤙💪
