It has been a splendid sunny day down here in Bournemouth, whilst the tempretures have been dropping, it was nethertheless a fine day. My original plan was to get essential bits-and-bobs done and out the way, so i could spend the afternoon working on the antennas outside, however the week had caught up with me and a much needed afternoon rest resulted in 2-3 hours lost, but at least I felt better 😀

Having had a rest I started work on the mast head amplifier, collecting all the parts I had stored away and the dremel, ready for making some holes. I had left my 9700 on 145.500 and was very surprised to hear a call out for a radio check ! Funnily this would be my first ‘ground’ QSO via the egg beater antennas and a good way to check that everything was working as expected. I had a great QSO with M0ABI who was portable in Barton on Sea, given I was using an eggbeater antenna for satellitle comms I was very happy to make this contact, and Mike had alot of history/knowledge of Satellites as well, it was a great QSO and I got back to work on my mast head amp.

Having place the mast-head amp in the ellectrial box housing and marking out where the bolts to attach it to the beam/scaffold would go, i then drilled two small holes with a dremel do it would line up nicely once in the box. I attached velcro supplied with the box to the back of the masthead amp. Its incredbly strong stuff and affixed the amp to the box nicely. I then screwed on the triplexer via a N-Type barrel connector.

With the triplexer and amp connected, i dremelled out the side-holes for where the feed line from the radio will come and the outputs of the triplexer, I stowed the 23cm output and kept a N-Type barellel connector on the 70cm output of the triplexer, as these are all PL259, hopefully this will make attaching the correct antenna to the triplexer easier once outside.

I checked out the feedline holes and am quitely confident the LMR coax I have will fit in there quite nicely. I have M&P Ultraflex10 for the feedlines to the eggbeaters between the multiplexer, to minimize the loss as mch as possible. I’m hopng tomorrows weather is at least dry so I can get outside and get the amp on the mast, then see if I can hear those birds just a little bit better….
