THE DELTA LOOP / MULTI BAND DELTA LOOP / SINGLE BAND DELTA LOOP

Описание: The delta loop antenna can be feed in different places to to change the polarization. This also shapes the antenna characteristics.

As a multi band delta loop antenna it will need a 4:1 balun or ladder line. A single band delta loop antenna can be feed with a 2:1, 2.5:1, or a quarter wave matching stub.

A single wave delta loop can be fed with a 2:1 balun or a quarter wave length of 75 ohm coax cable. You will have to adjust according to the velocity factor of the 75 ohm matching stub.

These antennas are known for lower noise on receive and better DX range on transmit.

I meant 50 ohm coax, not 15 ohm.
