Portable MW antenna? |
|
Hello all, it can be a silly question, but I'll try...
What do you think about "portable" antenna for MW? Of course with a tiny fraction of power irradiated (with a tx about 500 mW- 1W out) and 200-300 meters (at best) of rx radius...
With a car, is better a (very) short vertical antenna (1.5 - 2 meters) with a big inductor, or a magnetic loop with diameter circa 1 mt (and a lot of coil)?
I'm curious about your opinion..

Not feasible, can't bend the laws of physics.

maybe I've defeated the law... but my tx 0.8W whit a dummy load in very open space make about 100-120 meters.
Coaxial cable was only 2 meters.

MFJ 945E 1.6-60MHz 300W antenna tuner can work in the upper region of MW (1593 and up)?
Do you import Autek antenna analyzer?
Thanks!
