Increasing radio range? Or which radios have longer range if any?

My main experience with radio is military comunications. The frequency of our radios are changeable with thousands of available freqs. in HF and VHF. the difference in range between VHF and HF is notable, but we are talking a large freq difference here, not like the diff between 27 and 75 Mhz. And the atmospheric conditions play their part here.
Our newer radios (military) amplify the signal on transmision and recieving, so that a week signal being recieved is clearer than would normally be. The range of these babies is vastly improved over the radios that were used 20 years ago and they use less power to run.

the frequency doesent affect the distance?.....chey...dunno which idiot tell me one....
or maybe its because most 40Mhzs are the more Ex kind of controller thats why he thinks it can go further?
hehe...so dun flame me hor...

1. antena from the receiver must stay away from the power and signal cable of both servos.
2. antena from the receiver must stay away from any carbon fiber stuff, like radio tray.
3. Sliced the black plastic of the tip of the antena, expose may be 2mm of the copper wire.
4. use only one brand of battery for the TX(the point is to maintain same or similar power voltage and wattage, keep it consistant.
5. make sure all the batter is charged up and make sure you use good batteries like those NIMH rechargable batteries.
Number 1 is a very important! a friend of mine always have problem with receptions, but once he retie the antena and those servo's cables, it solved the problems!
Hope this will help!

I heard 75 goes farther than 27 too. And my Lynx 3d (75mhz) definetly went farther than my old Airtronics RTR (27mhz). Twice as far. My 3d (carefully) was used to about 200 + yards. I could barely see my Racer2 to turn it around.
What a run though, whew! ! !

Radio Range
Hi,
Generally speaking, the radio range does not depends on frequency in RC radio. What really matter is the power of the transmitter. Besides fancy function, expensive radio normally come with longer radio range as well. You get what you pay for.

Does slicing the tip of the antenna a little will help the range of the radio?
Did u try this?
