hardwiring a wireless camera to a tv

I need some help figuring out how to hardwire a wireless antena to my tv. The camera came with a black and white 5 in. display and I want to connect it to a 13 in color. Any sugestions... ANYONE? I connected The wires from the antena to the corisponding wires on the tv, but that had no effect. So then I thought maybe I needed to use both boxes.??

how do i amplify the radiofrequency of my 40mhz remote control so it will operate my receiver from a further distance? Answered

as some of you may know now, i am building an r/c tank, it operates on a frequency of 40mhz. now i have a problem, the old remote controller i had for it which i modified (by accident), has been thrown away after it stopped working (thanks to my un-understanding mother) the problem with this is though that i when i changed it around (i swaped some parts to make it work with aa's instead of button cells) it worked at 100m, the remote i have now though wont operate the receiver at any distance above 40 meters, so i want to know, where can i get a rf booster that will work for my remote control, sort of a thing that can boost the signal as it goes though the antena, or something, ive seen something like it in jaycars catalogue, but it only works on frequencies between 50mhz-1ghz, and it extends the radio coverage by 100m. since its only a toy remote i dont think it can be alterd, plus this one isnt the same as the chip transmitter i used to own, this one is a crystal remote controller.
