Antenna Routing?

[mechplas]

I am curious on how others mount their antenna and routing?

Lets see em.

Here's mine.

Are those aluminium boom supports? If they are then i believe u dun wan to run it that way, cos if i remember correctly, i read somewhere that aluminium causes interference.

You got me thinking here bro...!

Hmm...let me see, from my understanding any loose metal to metal connection that undergoes vibration can introduce RF that could cause inteference with the radio tx signal...yes?

What would the reason be for routing the antenna wire through the plastic tubing?.....Is it insulation or protection against physical damage?

If the antenna wire is not in contact with the alum boom in my case, (the antenna tip does not extend out from the tubing end)does that make it safe from RF noise?

Look at the pink heli in the pic above (Forum header), does that look like the same antenna routing as mine?

Now, I am really really feeling curious to know opinions on this matter. Thank you.

Hey mechplas

For what I know... It is metal reflect radio wave (just like those TV aerial). If u place distance correctly, u can get double multiplication of reception signal but in one direction. If your distance is wrong, u get 0 of the reception signal (Think of water wave on the pond... equal wave multiply while opposite wave cancel each other.

Routing antenna through plastic is to make antenna stiff. The reception is better when your antenna is in straight line. With that, u get a Whip antenna. For Whip Antenna, the idea length is 1/4 of the wavelength.

Remember... conductive material reflect radio wave.

So what you are saying is to re route the tubing away from the alum. So the original location (the skid arm) would be ideal? Thanks S-H.

Guys, i also route my antanne this way.
I will report to this topic if both my helis crash due to interference from routing the antennae this way. Been flying both my helis for many months now, so far, no problem.

I route parallel to the boom support within the attenna housing. For the extra bits that exceeded the length of the housing... I loop in around the screw holes at the servo horn ... (similar to the horn shown in mechplas's heli)

- kinda preventing the short loose end from touching anything I don't want it to touch.

No probs so far too... but I don't fly my heli far yet.

I am doing what mechplas does...so far so good....no range problems or glitches...

Hi mechplas

The recommended placement is away from any metal or carbon fiber rod. U can do whatever u want...so long as u are comfortable with it.

Yep! Been flying with the antenna routed similar to the other guys! .......Maybe that's what caused my crashes and not my darn fingers! .........I'm not such a bad flyer after all!!!!

[ammo]

To avoid any glitches, do not mount the anntenna near and parallel to any metal/alloy and carbon rods. It might not glitch now but it is something waiting to happen. advise u guys to re-route.

Hmmm... maybe I should reroute and next week I can do all the loops, flip flops, mow grass, autos, etc etc etc

Ammo and Super-Hornet: Noted your recommendations. How do you route your antenna?

Looks like I'm going back to the original mounting....on the skids. After all a safe heli is better that a stylish heli crash!

[ammo]

i route my anntenna thru a pretty long fuel tubing before the plastic tubing they provide. goes 1 round around the front skids before i insert the plastic tube into the skid holes. in this way this anntenna is protected from all heat and vibrations and contacts.
Oh yah, i manage to keep the full length of the anntenna within the fuel and plastic tubing and top it off with the rubber cap.
i then cable tied the very end of the plastic tubing to the right boom support just to keep it out from any rotating parts--> head?

I'll leave mine where it is.......so got excuse when I encounter my next brain and fingers freeze!!
