Spektrum Antenna ???

[ImBroken]

I was doing some research on the Spektrum receivers, when I came across this post on another forum.

I have a friend who's an engineer at Spektrum, and when I recently sent my tx/rx to him for service, he told me an interesting thing (after which he proceeded to cut my rx antenna) - the optimum RF reception is actually at half the standard rx antenna length, meaning that you get better reception with the short antenna length than with the stock one! The reason the antenna comes stock at twice the optimum length is because people expect to have a rx antenna sticking out of their car, and marketing/user tests found that when there was no antenna sticking out of the car, people got nervous.

I'm very curious if this is true or not.. I'll have to make a phone call...

The one in my beetle is completely under the body...I have had no problems with it?I probably took it 150 yards away from me...

I would like to hear more about this...

Hey Zandor!

Do you have your spectrum book handy? I have misplaced mine. What was the cut lenght in the booklet?


Thanks
Stan

It says 3.6'' In the book...With negligible loss of range

just read it!

Yeah 3.6" Mine is completely under the body on my LSP and so far no issues. Might cut it down on the Revo. Interested to hear back on this IB.

I like how they say w/ negligable loss in range.....LOL...like cutting a few hundred feet off a Rx range that's supposed to go further than you can see the damn car w/o binoculars.....we could probably all cut the damn thing completely off and still use them in our standard range of racing or bashing.....

I've posted this before in another thread and a bunch of people jumped on me for it. Having said that, the optimal length for a 2.4GHz antenna is 4.9 inches. The 3.6 inches is the minimum length outside the cover that you should have. I have mine cut to this length and I am able to run both my old Revo and my Prospec easily 300 feet away on level ground with no noticeable loss of control/signal.

The Nomadio system, from what I understand, has a different antenna and should not be cut.

I have cut mine down!!! No problems at all. I also have one with a broken off antenna from the circuit board. It only gets about 20 yards then no reponse from it,it needs to be sent back
