11m Cubical Quad Antenna

June 10, 2017 Admin 0

Written by M6GFT ::: QRZ Page- http://www.qrz.com/db/M6GFT Following on from my inverted V and pikey Skypper efforts, I have got the antenna building bug good and proper. I was going to call this the Pikey Quad, but I have decided that instead of doing this as cheaply as I possibly could (as I did with the skypper), I would just spend that little extra to ensure it can be built in such a way that yes, is much cheaper than buying one, but also that it works properly as as well as it can do. A good friend took me to ‘anchor supplies’ in nottingham last saturday. This is a huge army surplus supply store, sells allsorts. They advertised (on the website) some used army glassfibre interlocking tent poles, £15 for 25 poles, or £7.50 for 10. I sorted out 35 decent ones, and went to pay. The lady said she didnt know the prices so would phone up, which resulted in a total price of £12.50 Not sure if she counted them wrong (or not at all), as I was looking round the isles at other stuff. but I think thats a result. Had some aluminium tent poles in the shed, which just happen to interlock with the fibreglass ones, so might use some of each yet not 100% sure. Went to knights and got 25m of 14swg antenna wire, and a proper dipole middle with so239 (gotta be better than a tupperware container lol). So, I now need the boom, and other bits to connect the spacers to the boom, I best get designing quick. Mark DX, if you read this, could you PM me some details please of yours if thats ok. Also not 100% sure yet if the reflector loop needs the ends connected together or a spacer ? If anyone knows please pass me the info thanks as I can’t seem to find that online.

When i unpacked the handsets i got quite excited because they immediately say “Professional” to you and compared to Binatones other efforts they certainly are. I switched the radios on after a full charge for the first time. Using the top mounted On/Off switch which has a very nice sounding click to it and the radios powered up, They have the full frequency displayed on the orange backlit LCD display which looks quite striking. First i tried close distance comms and was not disappointed with the performance, from a distance of 200 meters in a built up area they excelled with great quality audio on both RX and TX. Next i tried the handsets at a distance of 1 mile in a built up area and again they made contact easily with no background static or crackle. With such good performance i wanted to go for a long range contact so my brother and I went on the moors with no buildings, trees or hills, just flat moorland. At a distance of 3 miles with no obstructions they made immediate contact, they performed equally the same at both 5 miles and 7 miles with no obstacles in the way. We decided to try 10 miles but this time there was a slight hill between us, I called on the handset and my brother immediately replied but with a small […]
