I hope the Wimo guys can claim for this from their courier as I need another one!
The guys from Wimo have been really quick on email and kindly sent out a new boom to fix my incorrectly packed antenna. This arrived at the Scout site on Saturday. The problem is that the box had a neat cut round the centre and the new boom is bent like a banana in two axes. I hope the Wimo guys can claim for this from their courier as I need another one! I took a closer look at the remaining parts to build the last yagi and found two potential problems. One is easy to solve – an element without a hole through it which I re-drilled in a flash. The second problem is not so good. The Driven Element has a tag on one side which I assume is used to align the elements and ensure they are all driven in phase. The problem I have is that I can’t align this DE with the other three in the stack without turning it round backwards! Three of the antennas have the DE tag on the left when the connector is facing forwards, whilst the final one has it on the right. Do Wimo produce the DEs in different orientations? Or has the tag been placed on the wrong side? How do I find out? I can’t use an ohm meter on a folded dipole…. Answers on an email postcard, please

I have been buiding some wimo yagis to use for JOTA,but have hit some problems with one antenna. Here are the parts laid out for the two new yagis that I bought. All looks well! But looking a bit more closely there is a problem with the boom sections. The top pair are OK, with the rear boom section at the very top of the picture and the front boom being the next one down. However the two sections supplied for the next antenna are identical. This photo was taken at the point where the DE attaches. Apologies for the quality of the photos! So, have I been sent 2 x rear booms? I think not. If you compare the top boom section and the bottom two then holes do not line up. This is at the D1 hole. I could have flipped the booms through 90 degree and redrilled, but as the picture below shows, the boom sections supplied are too short. So - I now have three antennas complete, and have written to wimo to solve the boom problem with the third. Let's hope the customer service is good...
Working 8P6 is nothing special, but it was nice to get 8P6DR, who is my HWCG club mate -G3RWL. Here's a video of a him working PY some time later! |
