Riped the antenna in two. newbie, how to fix

[lightningsti]

Hello,

So out running the truck and it rolled and slide on the cage. The antenna is now two pieces, almost the same size. What do I do to fix it? Yes it did have a tube on it but I will need to purchase a new one. The reciever is still good, because if I stand right next to the truck it will pick up signal. Thanks for the help.

Just strip back the insulation a little, solder the two pieces back together, then cover it with some heat shrink, you should be fine.

Thanks,

At first was not sure if that would work, thought it would just shorten the range, but I tired and it work well. Thanks again

Not to be the nay-sayer, but you are correct in your assumption that it will effect the range. I install Motorola radios into emergency services vehicles for a living so I deal with this kind of thing all day. The antenna length is cut to a specific length based on the bandwidth range of the radio, and by soldering the 2 pieces together you shorten the length of the antenna, throwing off the frequency range. Granted you shouldnt notice much of a difference, but your more likely to get interferance and glitches the further out you go. Just thought I would let ya know .

So you are saying that 1/16 of an inch or less is going to make a noticable difference? I really doubt that highly. And if the solder connection is done properly you should not have any glitching issues what so ever.

No, 1/16th is fine, 1/4 inch to half inch is a major difference. Ill put it this way, trimming a 800mhz band antenna 1 inch can take the frequency from 840 to 870, causing major issues with transmission and recive quality. If it is done correctly, as in 1/16th of an inch with solder, it should be fine, if any more than 1/4" is trimmed then it can cause issues. I apologize I should have been more specific .

I wouldn't piss around with soldering them back together recievers arn't that expensive or just buy a fail safe because your chances are a lot higher with getting a run away if you do that.
