Would there be any interference problems if I had to transmitters on my robot, but one is transmitting at 900 mhz and the other is transmitting at 2.4 ghz? I dont think there will be, but I just wanted to make sure.
Hard to say, as it depends on...Distance between antennas.Shielding on the respective transmitters.Modulation.Even the orientation of coils within each of them, but shielding and reorientation can handle such issues.SelectivityThis is assuming they're transmitting concurrently, if that can never happen, you just have to be careful with antenna positioning.
But why? using either/or would be more sensible.
Please use the correct terms. There's no such thing as mhz it's MHz, M for Mega (=1,000,000 while "m" means milli = 1/1000 or 0.001 an Hz is named from the scientist Hertz, so should be capitalized. Same goes for "ghz", which should be written as GHz.
Would there be an issue if I switched my transmitter from 2.4 GHz to 1.2 GHZ? Will there be interference since its a pretty close frequency?
Actually before buying the transmitter and receiver for the video transmission, would you guys mind if you quick checked over this product to make sure it will produce the results I'm looking for (clear transmission of up to 1500 ft). I am still a novice when it comes to wireless transmission. I just do not want to return this all the way back to China realizing this is not what I need.Here is the link to the ebay item http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=120811648140#ht_2065wt_1189
Transmission distance without obstacle：～2500m
Notice:For better reception, make sure that the transmitter and the receiver are placing at least 5 feet above ground. Distance affected by the nature of environment such as noise, weather, traffic, building, trees ... etcAntenna must be attached on the transmitter before power up. Otherwise, the transmitter will be burned out because the excess power cannot be released by the antenna.
