Hello all. I know now that 2.4 GHz is so popular that long receiver antenna runs are not all that common any more. But I still use 72 MHz… yeah, I think I still have a Commodor 64 computer and a slide rule somewhere too…lol. Anyway, I was wanting to use a Deans or Revolution base loaded antenna in a few of my planes but can’t seem to find a source to buy them from. Are they still available anywhere ( I need three of them... preferably the two-piece Deans type). If not, is there a reliable DIY method of fabricating one?

Never had a Commodor, but my pocket sized K&E Log-Log-Duplex Semitrig slide rule is sitting in my pencil holder on the corner on my desk:-)))))))))))))))))

As far as shortened antennas go, I am on 50 mHz, same kind of antenna problem, and I just wrap the excess length around a soda straw, and stuff it into the fuselage with a short pigtail hanging outside, so I can see that things have not migrated up into a bunch, somewhere.

You will get a reduction in range but on all these (27MHz, 50 MHz, 53MHz, 72MHz and 75MHz) you can get by in most cases by doing what Les says above. Just make the turns are as near the base of the receiver as possible with as much of the free end still straight out in a single direction and make sure none of the turns overlap each other. Do a range check before trusting any hi dollar plane to this but you are likely to get 500 ft. range or more, quite a bit more in some cases.
