1/12 coaxial match transformer...

[RADIOOMAN]

What if the antenna, tuned properly, presents a 35 ohm or lower feedpoint impedance, and thus a 2.1 or worse SWR?

The DB

That is a special case where you can use the 1/4 tx line transformer to transform the 35 ohms to the 75 ohms.
SQUARE ROOT ( 35 x75 ) = 50 ohms
Easy Peasy.

In the absence of the antenna analyzer, you can use a SWR meter, dummy load and coaxial "T" adaptor too. Connect the "T" directly to the output of the SWR meter. Connect the dummy load to one port on the "T" fitting and the unknown length of 75 ohm cable to the other port on the "T". Trim the open end of the 75 ohm coax until you have a flat SWR on the desired frequency.

wow now that is a great idea... I love this hobby
