Hi, Yes it's worth the upgrade, and all you caravanners with directional aerial, i have a new gadget that will be available in December, which is a TV signal finder, all you do is plug in your TV lead, move the directional aerial until as many of the yellow LED's light up, and bingo, you have the best signal for the area. I have been a caravanner for many years, and i have spent lots of frustrating time trying to tune in my TV, I work for an electronics company, so i have helped to develop this product. You can contact me direct if you want further information.
