    Ever since I've had my F-14 tx I've cursed that huge great telescopic aerial sticking out of the case. I've replaced it once after I caught it in a friend's coat and bent it out of shape, so after seeing Ramesh's F-16 with a much shorter helical aerial, I decided to try one out.

    Ramesh did confirm that he'd never noticed any loss of range with the short aerial, as yet I haven't had a chance to use it outdoors, but I've just done a range check by taking the Neptune downstairs out on the rear lawn, and with me upstairs operating the tx, everything worked fine on the sub.

    It feels much better than having all that tubing sticking out the front of the tx case...expensive though at £39.52 (that figure does include £2.50 postage)

    I bought mine through Westbourne Models in Dorset. Here's the link : Aerial and scroll down to the very last item on the page.

    I think that Ramesh uses a swimming pool a lot i.e short range.

    If you operate in larger bodies of water you may need the full length.

    (I do occasionally lose contact on the pond at Barrow so I don't intend to go that way.)

    And also we "Long Wave" users (along with the 27Mhz boys) can stand proud with our big aerials!

    Agreed David...as the part of our local lake that we are allowed to use isn't much bigger than a swimming pool, I think I'll be alright with the helical aerial. More so if I go walkies with the sub, and the exercise will be good for me as well...

    Remember the old saying..."it's not the length that matters, it's where you point it..."

    Just remember to keep the nut inside the Tx tight Richard. I used the helical aerial for a while and kept losing range. Eventually I traced the problem to the loose connection.

    Funny you should say that Andrew...I did give the tx a 'shake' test, and found that it did come loose, so I smeared a thin coat of Loctite over the thread before finally tightening it all up.

    So far it seems to work fine, as soon the weather improves a touch I can go out and test it on the lake.
