POLITICS, n. A strife of interests masquerading as a contest of principles. The conduct of public affairs for private advantage. - Ambrose Bierce

There is no giant behind the devastation of the world?only a shriveled creature with the wizened face of a child who is out to blow up the kitchen because he cannot steal his cookies and eat them, too. - Ayn Rand

=============================== Simplicity is the keynote.

Begin with a simple 3 to 10 feet whip.

Then advance to a 2 or 3 feet diameter tuned loop for directional purposes.

A multi-turn loop for VLF or a single-turn loop for HF and and VHF.

But to discover the presence of weak interference there's nothing better than a 50 to 150 foot Inverted-L with a very modest ground connection.

It greatly depends on the frequency of interest. Antenna sensitivity for initial ball-park estimation of field strength can be calculated from antenna dimensions with sufficient degrees of accuracy.

Receiver quality matters much more than the antennas used. Use calibrated spectrum analysers for important critical work.
