How to use auto CB antenna like a base antenna

On the table are : transceiver CB Avanti Alpha + EA35 + Zetagi MM27 and a DC switch power supply.

This is the RF shock made from the coaxial cable at ~L/4 = 2.6m, diameter of the coil is 3cm.

And that is a beautiful CB antenna Sirio Blue Line 3000, fixed outside the window at 40cm from the building wall, 7.2m high from the ground.

The SWR is 1:1 and the antenna take the power without any problems, so that cloud be a solution when you don't have the space to mount other base CB antenna, or you must improvise something quickly for an emergency situation.

An other good CB antenna is the Sirio Super S9, and in the test it was working well tuned only with the transmatch, no shock coil.
