Power Supply for the Mini-Whip active antenna

So, this is just a brief post to say that I have received the Mini-Whip power supply for the Mini-Whip active antenna project.
First impressions are not the best, it really looks and feels cheap, but for £1,99 shipped to your door, I cannot complain.
I took it out of the box and made a quick and dirty voltage measurement with no load whatsoever, just to see if it works. It reads 12,74V, a bit north of 12V but it should be fine to power the Mini-Whip.
Here are some pics.

So, the project is still missing some bits and pieces (a major local electronics store just closed; last weekend I went there to get some parts and it was just a waste of my time) but at least there's some progress.
Items still needed:

  1. I need a 12-15V small power supply, capable of delivering 50mA.
  2. I need 3 x SO239 (or BNC?) Chassis Mounting Female Sockets.
  3. I need some small 50 ohm coax (RG-316 or RG-188).
  4. I need to come up with some sort of PVC housing for the antenna.
  5. Also, I need some housing for the antenna supply module.
  6. Finally, after all is done I need to sort out some kind of a plastic mast to raise the antenna.
 So, hopefully, there will be more progress on the next weekend.

  1. This is an interesting project. And it’s good to see that it’s progressing well. It’s just a bit disappointing that you can’t continue your work because the store was closed that day. I just hope you found a different store where you can buy all the materials you needed. Anyway, how's it doing? I hope you’re close to finishing it, or already finished testing it.
