I wasn't trying to convince you of anything, I was just making conversation. You can believe in whatever you want.

Hey Andy,

Here's something I am pondering...

I see people who add heat shrink tubing to their antennas to hold them straight and in place.

Since heat shrink is an insulation with some dielectric strength, does it have a negative impact on reception?

Thanks,

JC

So far it hasn't affected mine any. What about all the polymers in foam?

I have heat shrink on some of mine still.Did a bit of testing with and without.
No difference whatsoever in Flightlog data so Id say its RF transparent.I was always afraid to put enough heat on it to make is stay on well enough and had a few fall off over time.I now mostly prefer Robart air line.

Thank you!

Does the robart line push on and stay on?

Actually, radio signals are attenuated with the square of the distance (i.e. doubling the range requires 4x the power). Think of it as the surface of an expanding sphere (the signal does not "fill" the sphere").

The version number is displayed on the third page of the system settings.

Hold down the scroll wheel while turning on the radio and scroll down to "system settings".

Ooops... I just thought the poster wanted to know how to check their current firmware version. What freechip said below.

go here https://community.spektrumrc.com/ and register your radio. Then download update onto SD card and update radio. Then you will be able to adjust the rx bar graph.

That makes no sense to me, I thought that due to the radiation pattern of the antenna you don't want to be "pointing" it to the receiver, (cause out of the top of the antenna is where the least signal strength is coming from) but with a straight antenna that's just what you are doing... (that is if your body is following the movement of the plane.) (unless like some of the "youthful" guys who seem to have made a silent agreement to hold the TX vertical against the body with the antenna pointing straight down... )

So what's the verdict on that then? (the way I point my antennas is 90 degrees to the side how's that?

What ever way works for you as long as you are not pointing directly at the model.

Works for me
My thought was that he was referring to the receiver antenna wires in this case, though I do believe I've heard of some folks using heat shrink tubing to fix a broken knuckle joint on the transmitter.

Hmm, yeah he probably IS talking about the receiver antennae, Since he's referring to reception range... I thought it had something to do with a broken knuckle (like the movable joint) of the antenna as well...my bad...
