Aerial Force set out an engineer promptly a few weeks ago. However, I was pretty concerned with the advice the engineer gave on the day. First he diagnosed a blown amplifier which was going to cost a further £70 to fix but after some more deliberations he decided I also needed a new mast top and associated power supply. He said he was unable to complete the task as the light was fading but he would come back and do the job for £300 plus VAT. I thought about it but thankfully did not commit at the time as I thought spending £360 was a bit excessive. I was proved right when I investigated myself and found a blown capacitor in my amplifier. I was then able to order a replacement for less than £2 on the internet and fit it free-of-charge! Had I not been so savvy (and luckily had the contact number of a family friend in the trade) your company would have pretty much ripped me off to the tune of £288.
