After sorting some of my pictures, I came across this one, and thought what a smashing picture and how long before summer arrives here with its lovely warmth and light and long days. I think the picture was taken in Chelmsford where we fitted a new TV aerial and satellite dish. The dish had to be high up the mast due to a large tree blocking the satellite signal, so on my sturdy 1” ½ alloy mast it was. Looking at the picture I can see the chimney stack was big enough to accommodate the large 5 brick course chimney cradle, which gives heavy duty support to the aerial for years and years to come. Cheap isn’t the best way forward and in the long term spending a few extra quid on heavy duty bracket pays dividends as the aerial stay where it is fitted and with stands our weather. A lot of aerial company’s still use the cheap and cheerful 6” chimney cradle which only takes up 2 brick courses of the chimney stack and with a 6ft steel pole fitted with an aerial at the top acting as a weight and the pole acting as a lever, it is guaranteed to damage the chimney stack as time goes on wearing the bricks away until the aerial comes down. Which is why I choose to use heavy duty brackets and know I have done everything I can for my customers?

I always use aluminium masts for 3 reasons: 1) they look nicer than steel, and they become a part of our customer’s properties. 2) Aluminium mast are lighter in weight and minimise weight to the chimney cradle and chimney stack. 3) Aluminium masts are lighter for us to carry up to the roof, why would we use anything else? The aerial in the picture is a Fracarro Log-Periodic w/b aerial which is my favourite choice of Aerials, as its construction and performance is fantastic!

The above information is one of the many reasons I choose to use Fracarro Log-periodic aerial, all aerials have a set gain and they all have dips, the Fracarro has a good constant gain, which in my opinion is a great aerial for my customers, and with its superior waterproofing we happy to guarantee it for 5years.

We still come across some of our customers who believe they need and ultra-high gain aerial and insist on having a monster put up when they are in a good signal area; too much signal can be as much of a pain as to little. If the signal requires a little lift a masthead pre-amp is our choice rather than heading down the 16ft 2” mast for height and an ultra-high gain aerial, but every engineer has different methods of getting signal.
