[TowerTalk] Antenna resonance question

[David Robbins]

I would say no, with a matched load on the feedline I would expect all the
power absorbed from the external excitation to be transferred to the load.
What are you trying to do?

Subject: [TowerTalk] Antenna resonance question

Hi folks - need some help.    A shortened 160m vertical ground plane antenna
is cut and tested for a resonant frequency of 2.24 Mhz.   The antenna is
matched near perfectly to 50 + 0j ohms at 1.85 Mhz using a shorted coax stub
of appropriate length placed at the appropriate location along the feedline.
With a 50 ohm dummy load attached to the station end of the feed line, will
the antenna be resonant (ring) when externally excited at 1.85 Mhz or 2.24
Mhz?

 

Thanks in advance for any insight you can offer.
