New TV Aerial Danbury Essex www.andysaerials.comPosted by andysaerials in Blog | May 27, 2013
New TV Aerial Danbury Essex www.andysaerials.com
Just sorting through my proud pictures of my work and found this one a new TV aerial Danbury Essex www.andysaerials.com how I could have not published it, as it is one of only a few pictures in sunlight! I received a call asking for a new TV aerial installation, and went there for a quote. I instantly realised with the height of the land the digital signal would be screaming in and wanted to use one of my favourite log-periodic w/b aerials. The roof was lovely to walk up and the chimney stack was a lovely little stack easy to get to and easy to lash. The stack itself was in need of attention so I lashed my heavy duty 13” 5 brick course chimney cradle at the bottom giving my aerial plenty of support and not aggravating the loose top course of bricks of the chimney stack.

We were absolutely delighted when our customer phoned us and was happy to go ahead with our quote for their flat screen TV wall mounting by www.andysaerials.com we had given a quote the previous Saturday and was happy to receive the call form our customer. The internal wall was solid brick so we had no issues with hanging the beautiful Panasonic smart TV. We needed to run an aerial point to the wall where the TV was to be hung, so after metering the aerial signal we fitted a combined inductive splitter with a set loss of -4db and ran a new aerial cable from the loft through the facia board and down a drain pipe, so it could not be seen.

New TV aerial Rettendon Essex www.andysaerials.com
Monday morning and were off to Rettendon for a new TV aerial install. We had already been and completed a site survey and quote a couple of weeks ago, and I had put up a TV aerial for my customer’s neighbour about 10years earlier, and when we arrive to quote I remembered signal was a problem. My customer had a Unix 52 on a 16ft 2” mast and very few elements remaining, I explained although most of the surrounding houses had aerials on 16ft and 20ft masts, I was not a lover of enormous masts and would go no higher than 12ft. When my customer called me to go ahead with the work I ordered an Antiference XG10 w/b aerial as I believed the XG10 would be my best choice given the signal difficulties with the area.

New aerial Ingatestone Essex www.andysaerials.com
Saturday 2nd call to Ingatestone for a new aerial, when we arrived there was an A group Yargi on a 6” chimney bracket which was wearing away the brickwork of the chimney stack. The roof was a long, long one with biscuit tiles, my roof climber was not long enough for this roof but with a little over leaning I got the ladder hooked on the ridge of the roof. The views were lovely only it was still over cast and no sign of sunshine. I collected from my van a large chimney cradle and lashing kit and set off up the roof to the ridge, walking along the ridge I got to the lovely little chimney stack, where I sat and made myself comfortable while I attached the lashing kit to the chimney cradle. With the chimney now lashed I put a Facarro log-periodic w/b aerial on an 8ft 1” ½ alloy mast and neatly taped the coax cable down the pole. I fitted the aerial and mast to the large chimney cradle and plugged the aerial into my spectrum analyser; I was disappointed to see 2 of the digital mux’s weaker than the other 4. The weak mux’s were 38db and the other 4 were 44db and I needed 2 TV points from the signal so I had to use a 2way masthead pre-amp. I decided to run the coax cable from the aerial into the loft and fit the masthead inside.
Satellite dish move Billericay EssexPosted by andysaerials in Blog | May 11, 2013
Satellite dish move Billericay Essex www.andysaerials.com
Saturday 1st call and its re-site a satellite dish as a neighbour’s new building extension has blocked the line of sight of the satellite dish. We arrived at 9:30 just in time to catch the rain, after putting on our waterproofs we asked if we could use the scaffolding around the neighbour’s house, as the neighbour was out it was fine. With the scaffolding side rails I was able to stand them and able to reach the chimney stack to fit a chimney cradle and lash it comfortably. Wanting to keep the installation neat I cut a small piece of 1” ½ alloy mast the same size as the chimney cradle for the satellite dish to secure to. The dish arm was facing the correct side so I did not have to un-bolt it and rotate it 180degrees, which was a bonus. After lashing the stack and fitting the chimney cradle I put the pole mounting brackets on the satellite dish, so I could just drop it on to the 1” ½ alloy mast. The beauty of mounting the satellite dish arm to mast between the bracket is, the bottom of chimney bracket supports the satellite dish giving good strong lasting support.

Satellite install Hornchurch Romford Essex www.andyaerials.com
Friday 2nd call and I’m off to Hornchurch for a satellite install. When I arrived there was a huge problem in the name of a tree, right in front of the house. My customer had his dish moved twice already and was tired of losing channels and pixelating pictures. I suggested a new dish on their chimney stack, giving a good line of sight and lovely pictures. The roof was a little tricky and decided to use my roof climber, once on the roof I could clearly see a position for the satellite on the chimney stack which would miss the problem tree.

New aerial Boreham Essex
Thursday last call a new aerial Boreham Essex, my customer’s aerial was a Yagi A group fitted on a ¾ steel mast and had snapped in half. Judging by the surrounding aerials the signal was in abundance as there were plenty of 10 elements around. The roof was an absolute dream with nice grass front for my ladders, and a large porch roof to prevent my ladders being blown to the right. With the wind as strong as it was I decided to play it safe and tie my ladders to the guttering just to be on the safe side? The roof was perfect to walk up, nice strong, grippy tiles with a lovely pitch to walk up.

New aerial Writtle Chelmsford Essex
Friday 3rd May last call nice and local an annoying aerial installation? When I arrived I was absolutely horrified to see the customer’s aerial clinging to their chimney stack by a plastic band, which was wonky and through the cement course of the bricks. The excess of the plastic band was not cut off and left to rattle and rustle in the wind, annoying my customer and their neighbours. My customer complained of poor pictures and was tired from being kept up at night, with the noise from the aerial installation; the aerial was on a 6ft ¾ steel mast and was not sufficient for a bungalow in Writtle which struggled for signal. The aerial cable was thrown down the roof and even went across the customer’s window. To add insult to injury the aerial cable was put through the double glazing! Who drills through windows? My customer produced their receipt for the installation and the engineer had written on it… ARIEAL UPGRADE! I went up the roof and cut off the excess plastic strap and resolved the noise issue immediately. I told my customers there was no charge and gave them a discounted price for a new aerial installation with a guarantee. I live locally and gave them what I believed to be the best option, and started packing away as I thought they would want some time to decide what to do. My customers wanted to have the work carried out so I took my ladders off my van and made a start. Once I had cut the aerial down I spotted the aerial coax cable where it fixed to the aerial dipole had been left unsealed as the engineer had forgot to put the plastic waterproof shield on.

I did not want to use either a 12ft 2” or 10ft 1” ½ mast unless I had to so I put a Facarro Log-periodic w/b aerial on an 8ft 1” ½ alloy mast, and took some signal readings with my spectrum analyser to see if I could work with the signal on an 8ft mast. The bottom digital mux’s were good, square and of a reasonable strength. However the top 3 were weak and was awkward losing dB’s as I rotated the aerial trying to get the 3 digital mux’s straighter. With a workable signal I secured the aerial mast to the large 13” chimney cradle and cut the aerial cable just over a meter down mast ready to receive a masthead pre-amp to amplify the signal.

After some thought and a smoke I decided to use a Televe’s 5351 masthead pre-amp/diplexer which is a fantastic bit of kit, with a 29db gain and the ability to attenuate / reduce the amplification by 15db with a noise figure of 2.5db it was perfect for my customers. I connected the aerial to the masthead and then connected the masthead to my spectrum analyser, using the spectrum to power the masthead with 12v I was able to reduce the amplification and reducing the noise levels to a minimum and keeping the amplification enough to bring in the top 3 digital mux’s in for a working level for my customer’s TV.

With the new aerial now balanced and a good working signal I removed the cable from the output side of the masthead connected to my spectrum and connected a new cable from the cable reel. I neatly ran the cable down the roof, cutting up the left over from the lashing kit to put under the roof tiles, pinning my aerial cable to the roof preventing it from moving. Funny enough I decided not to use the window to enter the aerial cable into the house, I drilled a new hole in the brickwork by my customer’s TV. I put a rain loop in the aerial cable and sealed the 10mm hole with silicon sealer. Once in the house I fitted a 12v 100m/a remote power supply unit and then made up a new fly-lead from the PU to the TV. I re-tuned my customer’s TV and checked the pictures on most of the channels. My customer was instantly delighted as the pictures were not pixelating and was watchable! I only noticed at the end the engineer responsible for the disaster installation had wrote on my customer’s receipt signal from Crystal Palace and not Anglia lol!
