Re: 2.5mm copper wire
Wayne,
Try googling "magnet wire" and select "Australia" in the search tools, there are a few there if all else fails.

Re: Windom Antenna Adjustments - help please
Well I had some time today to read up on antenna fundermentals and discovered something interesting. American articles on "OCF Dipoles" {see.. PC now !} use the formula of L= 468/F (Mhz) e.g. 468/7.1 Mhz = 65.9154 Feet However, I use the more scientific measure of a metric (rather than th...

Re: Moonshine
Thanks for sharing this with us Chas and very well done.
Would you happen by any chance to know what the point of the exercise was?
I looked at it briefly and quickly put it in the too hard basket so good on you, how did the grid pack and 60cm dish do?

Re: Rack and pinion - where to get?
I don't know what sort of load you invisage but there is a plastic rack of considerable length in electric car antennas that might fit the bill?
There should a few around that have been broken that you could play with cheaply.

A hb9cv or a zl special will not give you as deep a null as what I proposed but it is on the right track.

Re: 2 element 10m yagi, which should be the parasitic elemen
Wayne, as I understand it which is by no means gospel. If it is absolute gain you are after a director yields slightly more but poorer front to back ratio. If it is front to back ratio you want then the reflector is a better option with ever so slightly reduced gain. An end on dipole without any fee...

Re: Mobile noise in Toyoto Landcruiser
Hi Brian,
There was an article in the September 2007 AR magazine dealing with the noise in a 100 series Toyota it is on page 20 and almost a total cure was achieved. The claimed result was a reduction from 10/9 to about 1/2 an S point on 40 Metres.
Cheers
