Just to say a massive thank you all the help and advice. I can't recommend your company highly enough. The antenna was just as described and although I was a little apprehensive being new to amateur radio. After reading the instructions the antenna more ore less builds itself. As you advised it fits a narrowboat perfectly and is surprisingly light and easy to manage. The pictiure shows it mounted about 3.5 m above ground, from opening to finish took 20 mins singlehanded. I cannot rate the product and customer care highly enough. Will deffinatly be buying again when I need another antenna.
Many thanks Ian
