[Elecraft] NVIS HF vs VHF line-of-sight & CB

[Walter Underwood]

The potential Cascadia earthquake could be 9.0. That means that every tower will fall, maybe even those built like this CHP/CalOES tower.

That is why I suggested easily erected wire antennas and small beams, like a 10m Moxon. After the big one, it will be Field Day, not “flip the switch on the linear”.

Regular practice with field antennas will be more useful preparation than a big antenna farm. Maybe some regular exercises with a Par EndFedZ antenna, or even SOTA activations.
