2m/70cm antenna – on a flag pole

To free up the buddipole for HF, I wanted a 2M antenna for the ICOM 2200-H I could use with ease. I investigated making a copper J-Pole, or Super J-Pole to be more precise, to increase the gain and range. Having worked out the costs, which after equipment, tools and consumables came to almost £100 !

With that I took to the internet to search for an alternative and found the MOONRAKER WTZ-270 J POLE ANTENNA for £37.98p (including shipping & VAT). So I already have the coax/connectors and a flag pole for hoisting it up on.

First job was to check the S.W.R. (I punctuate S.W.R where I can after I got caught saying SWR rather the short for acroynm – I’m not on 27Mhz here ;). I connected up my analyzer, and sure enough right in the 2M and 70cm a stunning reading of 1.3 SNR.

The flag pole has a decent plastic top, so I bolted the antenna to that, giving it isolation from the aliminum pole.

Now I quite forget how tall this flag pole was, but its a heck lot talller than my buddipole is, so I made sure that the weights were securing it. For the moment this was ok as I was supervising and it wasnt windy. I gave the mast a really good tug and with my weight it wasnt falling over anytime soon. The antennas weight with the bracket was very light, so no concerns there.

With that I headed in to my trusty Icom and started going around the local repeaters. I was not disappointed ! Immediatly stronger signals and clearer reception. A tried all the local repeaters and gateways, no problems there… So i thought, time to really test how far I could get on 10W, and tapped in the Southampton Repeater… amazingly it worked ! I got someone on /M and we could both make each other out, whilst not 5/9’s it was good enough and the furthest I had ever got on 2M and 10W – I think height and the antenna really done well.

So forecast for the weather in the UK this weekend is for high gales, and whilst I the mast & antenna are a good distance away from the public and buildings, i thought why risk it, and have taken it completely down tonight.

Good news is that will mean pictures for the next post, and maybe even a video – especially if I can reach Southampton again on 10W which is a good 30+ miles away and with some big hills between us.

Calling CQ on 2M.. its a bit quiet

I am very lucky to live near a really well connected simplex gateway, namely MB7IFD, which connects into Echolink, DStar and regular FM. It is has quite alot of activity thruout the day as I listen in casually, and tend to make my QSO’s in the evening.

Whilst I like the Ferndown gateway, I do try and get on the calling frequency, namely 145.500, and trying to make a ‘local’ contact without the use of the repeaters/gateway. Its not that I dont have anything against gateways or repeaters, but in a full over on frequency up from the calling frequency you are free from timing out and using the repeater from too long in one go.

So for now I’m going to keep trying, i might publicise when I’m actually going to go on, that my attract some listeners and get some local QSO’s.

IIn the mean time, its back to 145.2125 and MB7IFD.
