Replacing an ariel on Novak XXL
 

Hi,
I have been getting completely random interference for the last few weeks, due to a dodgy ariel on a 40 mhz Novak XXL. At some point the original ariel has been replaced from the pcb (not by me), and I think this is the cause of the issue. Before I go taking it apart, is it really that simple as soldering it back on?

I read somewhere that the length of the ariel tube can affect performance, does anyone know anything about this? Any advice would be welcome before I go taking it apart and ballsing it up.:(

Cheers

Lloyd

Yes

there is tuned length for the wire but not sure what it is

if you make it longer than the stanard ariel tube, say 1 to 2 inches you won't be far out

use a fine tip soldering of no more than 25w

The following are measured from the PCB:

KO297FZ 40MHz FM - 33cm
KO301F 40MHz FM - 33cm
KO302F 40MHz FM - 33cm
Futaba FP-R103F 40MHz FM - 36cm
Futaba FP-R122JE 40MHz AM - 40cm
Futaba FP-R122JE 27mhzAM - 38cm
Novak XXL 40MHz FM - 45.5cm
Hitec HFS-03MM 40Mhz FM - 43cm
Jamara XT2 40Mhz FM - 45 cm
LRP Phaser Comp 87400 40Mhz FM - 34.5cm
Acoms AR-2/27 mini RX 27Mhz AM - 48cm

The following are measured to the OUTSIDE of the case:

Futaba R142JE - 40Mhz AM - 49cm
Futaba FP R102JE - 27Mhz AM - 47cm
HPI RX1 - 27Mhz AM - 49cm
Spektrum SR3000 DSM 2.4ghz - 21cm

Cheers, I will measure it now. Not too sure if I trust my soldering skills though! He he......

Should be simple to replace the wire it's just a small solder job, if the wire was cut shorter than when it was bought new it can affect the reciever sometimes, the best thing to do is put a new full length wire in try it then cut it a little longer than the one on the table that chequered flag racing posted then cut off 1cm at a time trying the car each time till it's working perfect and not glitching.

That sounds like a good idea. Can I get the replacement ariel wire from Maplins etc?

any good model shop should be able to supply you with reciever aeriel wire, usualy get mine from dms-racing when i've needed to change the wire.
