[TowerTalk] 3.78 Mhz 4 square with Vertical Dipole

[Natale Borghetti]

I am considering to built a 4 share for 3.780 MHz by 4 sloping 1/2 dipole supported by 140 feet tower.

I have just simulated the system on EZNEC...but my results...contradict..what comtek suggest (to tune the 1/2 dipole 5% LOWER then the target frequency)..because when ALL 4 dipole will be in place the 4 square resonant frequency will be higher...

By simulation on EZNEC I saw exactly the opposite...seems the frequency of 4 square is LOWER compared to the single Dipole....

I am....making..some mistakes ????...or...wrong..interpretation ???

Any 80 meter Guru..could Help on clarify the..strange results
