Replacement antennas?

[csisfun]

OK,

Does anyone know where I can get replacement antennas for the Hitec Electron 6 and the Hitech Supreme (8 channel)? I'm looking for the 72mhz ones.

Any ideas?

The antennas are all wires only right ? Just re-soder can work already right ? This was what i believe they are.

Rotor sells them, abt $2, cut them to the correct length.

[PhiBeR]

U can probably cut wires to the exact length as the old ones..
or u can get exact replacement for ur mhz from rotor..

As the wires are cut to length for different frequencies,
u have to make ur the length is correct else receiving prowess
will defintiely be affected.

besides the length dose the type of wire play a part too ?

Antenna Length Calculator

Hi,
I checked out our legalised frequency on 29mhz. The antenna length is about 100 inches, Almost 2.something longer than 72mhz. Puzzled

Hmmmm......same here used the calculator to check on my 27FM and the result is 103" wow that is like 2.5m long of antenna is so much longer than what come with the std JR Rx !!!!! Besides 2.5m of antenna how to keep inside the plane.... and if hang out.....

Hi all

What u calculated is the lenght for 1/4 wavelenght. What u have in your RX is cutdown lenght.

[Tele]

that is given in 1/4 wave ...Make yours 1/8 or 1/16 wave

just by divide by 2 each time to get it the right lenght

as long as your keep it as a ratio of the correct full lenght its ok.

The lower the freq, the longer the wavelength...basic physics...nothing to be puzzled about...

Deans Antenna

Has anyone tried the deans antenna? It would shorten the length required for the RX antenna?

Was considerig since the 29Hmz's antenna is so long I'm kind of buffled as to what to do with it....

[Super-Hornet]

I don't think u can find dean antenna for 29MHz in Singapore leh. Rotor only has 40MHz and 72MHz.

What u calculated for 1/4 Wavelenght should be consider as desired lenght. If u can't use that lenght, what u can do is:
1. Use whatever lenght u want and then replace the remaining with Inductor load instead. There is the formula for it. Can't remember liau.
2. Another method u can use is that u coil up the access wire lenght onto a non conductive/metalic material (like act as a inductor)

Whatever u choose on the above, I would still recommend u do to range check first.

OK. Will try that.
