I had to use a bigger cable gland for the power connector as this was a mini din, however I still had to remove a small amount inside the cable gland and remove some ridges off the mini din plug, so it would go through the cable gland.Īs the housing does not have flat bottom inside, I had to make a plate to mount the amplifier on to. I have fitted the housing with cable glans, left one for the power connector, centre for the antenna connection and the right one for the power connector, and no crosstalk. This housing on the other hand leaves loads of space. So make sure the audio signals are individually screened! and the housing is big enough! This was not a good idea, I found major crosstalk issues. Another advantage in building a test version, was to ensure the RJ45 screened cable would work. This is the test housing I chose for the amplifier to live in, and was way too small, as can bee here on the left. Here are some pictures of the construction so far, click on the pictures for a larger version.Īs the amplifier has to live next to the antenna the housing it needs to be weather proof. The amplifier was brought as a kit from Daniel, I believe he is supplying kits as well as fully built versions. The only solution I could come up with was to fill it with plaster, a hour or so later, one solid antenna :-) I'm not sure how this will fair in the winter, but it will have to do until the next antenna is ready. Once the antenna was placed in the pot I had to fill it with all the scraps of metal I had. So that is where the Christmas tree pot comes in. Problem being, I could not screw it down, nor attach it to a soffit. The only other place for it is on my flat roof. The antenna should work fine in a loft/attic, however my loft is only just offer a 1m at it's highest, so there is no way the antenna would fit. It uses a few bits of wood, some wire, a Christmas tree pot, tool steel, lead and plaster. I started with building the basic antenna. One disadvantage is it will be heavy, as there will be around 400m of 1.5mm2 of wire in it. The other big advantage of this antenna design is higher gain and higher Q than both the original designs. There is a version of the antenna he designed that requires access to a lathe and pipe bending tools, however the new design only requires basic skills, like being able to cut plastic pipe and thread around 400m of cable through the pipes!! so patients is needed. He has just come up with a much better design which is very easy to build. The design for this comes from a chap called Daniel. So far it's taken me a year, and I have only just got it up and running! But it's not finished, The first antenna frame I built is made from wood, and although it will suffice as a test bed, I doubt it will last more than a couple of years, so I have started work on the final one. After reading his articles on the subject I thought I would give it a try. A Lightning Radar, this was designed by Frank Koofman. Here are details on one of my latest projects.
