nulling out the QRM West

Rx Ant to the West. Simple EWE 5m x 10m

Why I am "deaf" to the East on 160m

80/160m

Layout of inverted L

As well as the radial system the antenna is 1-2 miles from the Sea and on a bed of wet clay.

SWR = 1.3.1 @ 1810MHz 1.0 at 1825MHz 1.4.1 @ 1840MHz

Radial Mat. 4-5km

100+ radials, (5km) the majority 1/4 wave. Some 1/8 wave and 16 x 1/2 wave

Laying lots of radials (an easy way)

Simple 2m loop RX Antenna

Based on this design

http://www.hamlife.co.uk/getFile.asp?categoryID=3681&cCID=6858&fFID=594

provides a deep (40db null) on power station QRM 1 mile away.

Useful on "bad nights" /High Angle. KD9SV Pre-amp needed.
