receiver antenna broke...help

[bashmaster]

i have an older t-maxx and with the stock reciever.
the receiver's antenna broke about an inch and a half from the receiver itself... could i just crimp it back together or should i solder the longer peice to the circuit board or do i have to buy a new rx? :dumb:

This happend to me once with my tc3, I was able to solder it at the receiver, I wouldnt recomend crimping it, tried that too, very frustrating!!!!

Try soldering it, it can't hurt. If it don't work then u know u need to buy a new one. But by all means don't crimp it.

It'll still work if you solder it where the 2 pieces broke. Just don't shorten it too much. If you do, you'll sacrifice a fair amount of your radio range....

thanks, i saw on towerhobbies that you can buy sections of antenna wire. could i solder that extention on and not have any fear of sortening radio range?
:dancin:

I've had the same issue. My fix was simple. Find out the exact length that the antenna wire needs to be from the manufacturer. Take apart the receiver case and resolder the antenna wire on. No second guessing range etc. It's an easy one to do. Your lhs or hardware store will have the wire.

:yes: sounds good
thats my plan thanks guys

Make sure to pay attention to how long it was. The length of the wire is a "tuned length". This means that it is specifically cut for the bandwidth/frequency of the transmitter/receiver it's on. It isn't like it won't function with a different length, but it will not function as well as it should.

Also, don't solder the wire back together. This will cause wave-form interference. It's hard to explain but basically it will be creating a permanent glitch in your radio which also will probably cause issues with distance.

BTW-I'm an electronic engineer. I had classes on this stuff. Even though it was 8 years ago. Now i write software, but i don't think that will help you much.

hey olds97_lss thanks for the proffesional input its greatly needed, iwas gonna solder the wire back together. now I'm gonna get the new wire. :thumbup: :clap: :marshall:

The other reason i said anything is due to a friend of mine doing the exact same thing. Since he came to my place for bashing, it makes it difficult to take a quick ride to the hobby shop. I live 60 miles from the closest one.

Within 10 minutes of our bashing session, he rolled his t-maxx hard. The antenna tube got between the rollcage and concrete and was sheared off with about a 2" antenna left. He couldn't go more than 20 feet.

So we tried using a couple different kinds of wire i had on hand considering the drive it would take to get to the store. I didn't have anything that was real close to the gauge of the original and what i did use would fit the antenna tube. It still wouldn't go more than 50-100 feet without a lot of issues.

We also tried soldering the pieces back togther of the original. This didn't work very well either.

Just thought i'd try and save you the hassle. Apparently the classes i took were correct in this instance.

I'm getting the the wire from my lhs tomarrow so ill have it fixed and put back to gether and have it finally runing again

thanx for all the help
