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.

Sorry, did not read carefully and did not see what range you wanted. As a general rule of thumb you need a big antenna to have good range on MW band. A couple hundred meters might work with a smaller type. Antenna tuner might be usefull.

With this balun you only need to add wire to make a half wave dipole.

It covers well below 1.8MHz no problem.

many thanks for suggests, I've see some interesting objects, too

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!

Its usable under 1500 as well. We have what's there for now.

One approach to reducing the physical length of the antenna is to play with the electrical length through the use of tuned loading coils. There are losses, of course (damn physics!) but you might find a trade off you'll accept.
