Topband: 160m antenna help

[Paul Mclaren]

Looking for the advice of the experienced hams for what if anything I
should do to make my 160m inverted L more efficient.   Being realistic I am
limited as I have a postage stamp garden so can't really lay more radials
or change much beyond the inverted L.  I guess the question is would some
sort of match at the base help?

Antenna is inverted L with 18m vertical section

Radials are approx 40 x 10m lengths and a layer of copper mesh out to about
5 metres from the base as well.

Using my RigExpert AA30 analyser the readings are:

Usual TX frequency:

Freq 1825khz:    SWR: 2.6, R33ohm, X 31ohm, Z 44ohm, L: 2700nH


Lowest SWR is:

Freq 1882kHz:   SWR 1.7, R72.5ohm, X20.5ohm, Z77ohm, L: 1900nH

I'll be honest and confess I don't fully understand how to best optimise
the antenna and what "good" looks like particularly on the low bands.

Help please and thanks in advance.

Regards

The antenna works but no
