MF/HF Receiving Wire Antennas

Introduction

Receiving wire antennas are useful on 160 and 80 meters, where rotatable antennas are impractical for all but a few lucky hams.  The noise is so high on these bands that efficiency can be sacrificed with a negligible effect on receive signal to noise ratio.

Receiving Flag Antennas

Flag antennas are ground independent receiving antennas optimized for a good front to back ratio on one or more ham bands.  They are typically as small as possible to allow use in small back yards or to be mounted on a rotator.  The small size results in a very low gain that makes them unsuitable for transmit as well as highly susceptible to common mode noise.  But, if properly done, they may dramatically improve receive performance on the low bands by nulling noise via the deep null off the back of the antenna. Adjusting the termination resistor will optimize the depth of the null and a rotator will allow precise aiming of the null.  Normally vertically polarized, they can also be mounted horizontally to null out vertically polarized line noise.  They can be suspended between strategically located trees.
