Description
On offer is one of the many Hills 2 metre yagis that I have used over time. It is in used condition but still very good. A picture included here reveals what frequencies this yagi was designed for.
Note that the upper frequency limit was 144 Mhz.
It was not until about ~ 1980 when I was working closely with the Late John Mitchell VK5ZJB/VK5JM who had worked on the Apollo Missions, both Woomera and Honeysuckle Creek stations, that this 5A yagi could be trimmed and tuned so easily to the 2m band, with just a few small snippets taken off of the element lengths (shorten the length, to raise the frequency) to 146.5 Mhz covering our VHF band completely.
How convenient.
Those measurements I will hand a hard copy to any prospective buyer
.
So we experimented with our newly found observations, cut the elements to varying lengths and, field tested the signals at various power levels between Morphett Vale and Ardrossan, straight across a very clear path over St Vincent Gulf.
Result; we could not split the difference between other commercially made 11 element 2m yagis specifically designed for 2m and, our modified 10 element Channel 5A yagi which was cut to 146 Mhz.
An Australian manufactured product which was dedicated to 2m during that era, claimed a 14.5 dbi using 11 elements. This Channel 5A is so close, measurements can not differentiate it between other commercially built yagis, even those from the US with field strength measurements !
All that is needed to get you up on air is a nice ¼ length balun, either wound or folded, and away you go. I can supply the 75 Ohm coax feedline and crimp/solder connectors if needed to complete a balun. Too easy.
An example is supplied here with one picture revealing the NOS antenna against the used one. The NOS is a pearler never touched, but is not available in this offer, just an example picture.
So this used 2m yagi is available at a very reasonable offer and, it has a brand new mast clamp.
Unfortunately, it can be pick up only, as the boom length is around ` 3m, unless you can arrange your own courier.
Payment can only be made with Direct Deposit or Paypal prior too or at time of pick up.
So TKS for looking, I look FWD to your interest in VHF.

Oh, and please see my other listing for the 70cm 27 element BEAST !
P.S. Please excuse my typos, as not everyone is confronted with their 80th coming up on the day of listing. : - (
