Wet and Windy – but some action on 40m!

tuned into 40M

So the bad weather continues in the UK, i had wanted to carry on with my 2m/70cm antenna project but with the gales, it didnt seem like a sensible thing to be doing, esp as the mast is tall and heavy – even with a light breeze, it could be dangerous.

Instead I looked thru the Buddipole in the field document and reviewed the 40M section. It said it was possible, albeit with a slightly higher SWR.

its 40m but at about 2m in height…

So with the bad weather I got the buddipole setup, not wanting to lose any more antenna, I kept the height at about 2m verticle and guyed down the mast as usual and also thru the veresatee to give some extra support on the horizontal element of the dipoloe. This worked really well as the winds did pick up and mast held up well in the eright location.

I was only able to get my SWR down to 5, probably due to the height of the antenna, but amazingly I was able to receive ! Given I’ve not had alot of action on the Kenwood I was so happy to tune in and listen in. Some points I could get both ends of the conversation, others just the transmitter, but nevertheless, i found it a worth while excersie in setting up the antenna in inclement conditions and also being to use the Kenwood on HF.

Do some more investigation, one other configuration I could try is a ‘NVIS’ on 40m. This is well documented here and as I’m short one wire and the clearance mounts will probably do it another day (having just got over a bad cold, dont want to risk getting ill again !)

So for now here is a video of one of the many stations I could pick up on 40m. It was great, and amazing to see how the sun going down quickly effected the transmisions ! (80m is popular after sun).

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.
