The second picture shows the pre-amp mounted on the antenna frame. With out this it would be difficult to get both boards in the hosing. Here you can see the pre-amp and the humidity sensor boards mounted, You may notice I also built a false floor, which is set, just about the 1wire RJ45. This problem afflicted the last radar I built, so this time I thought I would keep my eye on it. If any moisture gets in then the humidity sensor should indicate this. I also put some silica gel in the housing to make sure it starts off dry. I have fitted a temperature and humidity sensor on the housing, see the second picture, this allows me to keep an eye on the state of the housing/amp. The two sockets on the right of the box are for the signal/power cable, this is the yellow one, and the other is for the 1wire sensor/s. The two glands on the left are for the antenna windings to come into the housing through.
The following show the build of the pre-amp housing. Lastly the Sockets, Regulator and RJ45, done. Now on to the controller, this was even more simple. ResistorsĬapacitors and Inductors, IC sockets Leds. Then for a coat on paint, well about three, this was mainly put on to protect all the plastics from the Sun's UV radiationįollowing is the start of the pre-amp build, quite simple, and easy to understand instructions. It does not look pretty but does the trick. I'm not the worlds best fibre glasser!, but I got there, this made a real difference. All this was very messy, which is an understatement. I also have found an issue where the top of the centre tube is a little too flexible, so I filled the tube with a resin, this worked very well, without add a lot of weight. You can also see from the two following pictures the two short uprights to mount the pre-amp housing on to. That did the trick, not the most pretty solution, but certianly very strong.

Here is the main parts of the antenna, plus a dry run of the fitting of the spacing rods.Īfter finding that the fillets were not ad-hearing to the main poll that well, I decided on fibre-glassing them. I drilled 6 holes to allow the two windings and spacing tubes to be fitted. I used a 40mm waste pipe for the main upright. Make it out of plastic!, all the parts are quite easy to get hold of, mainly waste pipe, 40mm and 20mm plus a some 10mm plastic sheet! So to the new I came up with a very simple solution to solve the problem. The first issue was I needed a replacement aerial, not this time made from wood. I have found another project on the same lines, so I made the decision to move on to it. Well in fact due the original project stalling, sadly the developer passed away, and will be sorely missed. I decided to build a new Lighting Radar aerial, the last one succumbed to the wood rotting.
