Update new 4 square 3,5 Mhz

 

Yesterday i found some time to try to improve the new 4 square for 3,5 Mhz.

Like i wrote ealier, the feedpoints are 2 m from ground, and today i brought the radials higher up in the air 

( 4 m high now, gull wing system).

The impedance at each element dropped from circa 46-  48 Ohm too circa 38 - 39  ohm, so less losses to ground, 

( a vertical should have 36 Ohm in theory) so the efficiency of the array is improved.

I noticed a bigger front to back now , specialy to close by signals ( 0 - 400 km),this is what to expect with just one radial for each radiator.

 

Keep you posted.
