New Beam, but not for me thanks

Thanks (again) to Southgate News comes information about a new beam from SteppIR. Covering 40-6m I am sure it will appeal to some. To me it is still huge and my neighbours would be appalled. I prefer to use low power and simple antennas. Luckily we are all different!

2m/70cm beam down

After about a year of service, I have taken down my beam for 2m and 70cm which was not working as it did. In the near future I want to erect big-wheels instead. According to Wimo literature they have an omni pattern and a single big-wheel has a gain (horizontal) of 3dBD. Spacing between a 70cm big-wheel and a 2m big wheel needs to be 1.5m. This gain is a little down on the beam but needs no rotating. At the moment I think I'll install a single big-wheel for 2m and one for 70cm both fed with low loss coax on a single mast as high as I can. These should suit my operating fine. I monitor beacons and take part in some 2m and 70cm contests from home in a non-intensive way. A couple of big beams would be nice but these would need a rotator.

Coat hanger 70cm beam

Some years ago, I was in need of a 70cms antenna for portable use and had to improvise by raiding my XYL's wardrobe!  The result was a 2 el Moxon antenna made in about 30 minutes which worked some impressive QRP (2.5W) DX into France on 70cms. Gain is quite low but all you need is a wire coat hanger and a few bits for insulation and to attach the coax feed. Simplicity! It does not look pretty, but it works. The mast was made from a short length of PVC pipe.

3 el/5el beam

VHF/UHF beam with V2000, 2m halo and HF Par antenna behind

The dual band 2m/70cm beam is erected and is working now the useless Moonraker crimped coax connectors at both ends of the low loss Westflex coax have been replaced by decent soldered connectors. Andrew G6ALB also restrung my Par 10/20/40m end fed back up so I am now operational as follows:

630m Earth-electrode 15m baseline

40m Par end-fed
20m Par end-fed
10m Par end-fed

The Par also matches on 60m and 30m via the auto-ATU.

6m V2000 vertical
2m 3el horizontal and halo
2m V2000 vertical
70cm 5 el horizontal
70cm V2000 vertical

This means I am decently equipped for the bands I am mainly interested in. The dual band yagi is small and cannot easily be seen from the front of the house. The most I run is 5W pep, although I use 2W mostly and just 5mW ERP on 472kHz. 2W is more than enough to be copied all around the planet on 40m, 20m and 10m.

2m/70cm antenna

Today I unpacked my 3/5el beam for 2/70cm, the wall brackets and the coax leads. I am missing a small SMA female to SMA female connector  (just ordered from eBay) to join the 20m long Westflex coax to the small patch lead to the FT817.

As far as I can tell, I have everything I now need, when the SMA connector comes. I shall have to wait until Andrew G6ALB can come over to help with the wall brackets. At the moment my health is still too poor (too giddy/clumsy)  to do the erection on my own, sadly.

VHF/UHF antenna arrives

A large package arrived today: my 3el/5el VHF/UHF beam, brackets and feeder cable. I must now await Andrew G6ALB to help me erect it.

We have grandchildren here over Easter, so I am hoping Andrew can help next week or the week after in time for UKAC Tuesday evening contest sessions. I am quite looking forward to having some modest gain on 2m and 70cms SSB/CW/digital. I gather there are also Sunday and Wednesday activity sessions on 70cms.

HUGE 160m 3el yagi antenna

Take a look at this antenna for 160m and 80m. It is the antenna used by OH8X and is absolutely massive.

This is certainly not my idea of ham radio, and the complete antithesis of QRP, but you have to take your hat off to these guys for the engineering of this monster beam which weighs tons. I wouldn't fancy scraping the ice off in mid-winter!
