denger2 di jogja ada....coba kontak mas Thoha kali ada infonya...
btw, walau sama-sama 2,4 ghz antara remot dg sender kayaknya g' akan ngobrol tuh.....

kemungkinan bentrok itu kecuuiillll sekali, kan dia punya kode2 unik utk masing2 pasagnannya... eh tapi bisa juga... kalo 2.4gz nya rusak/mutunya jelek, ya mungkin aja bisa bocor freqnya...
paling safe sebelum terbang dicoba aja dulu...

tidak dianjurkan pake video Transmitter 2.4GHz dg RC 2.4 GHz
meski mereka menggunakan coding yg berbeda
biasanya masih rawan interferen
untuk Video Tx 2.4 Ghz pasangannya bisa dengan 72MHz
Kalau Tx 2.4Ghz video Txnya pake yg 1.2Ghz atau 900Mhz
gangguan itu biasanya terjadi ketika terbang semakin jauh
saat terbang dekat gangguan blm terasa
yg penting utamakan keselamatan
Here is a list of the pros and cons of the different frequencies:
900MHz and 1.3GHz
+ Less influenced by obstacles due to lower frequency
+ much less “crowded” frequency
+ Works with 2.4GHz RC transmitters
- can interfere with GPS signal
- hard to find antennas
- not that many transmitters/recievers to choose from
2.4GHz
+ Easy to find a wide variety of antennas
+ Many transmitters/recievers to choose from
+ Doesn’t interfere with GPS as much
- More influenced by obstacles
- More “crowded” frequency
- Don’t work with 2.4GHz RC transmitters
5.8GHz
+ Easy to find a wide variety of antennas
+ Doesn’t interfere with GPS as much
+ Works with 2.4GHz RC transmitters
- Even more influenced by obstacles
- More “crowded” frequency
- not that many transmitters/recievers to choose from

A 1.3GHz 300mW transmitter
Ok, now that you’ve chosen the frequency you need to know how much power to get.
“There is no such thing as to much power” - Or is there?
A transmitter with higher power will:
+ Have longer range
- Be bigger
- Be heavier
- Produce more heat and may require a heat-sink (even more weight)
- Draw more current
- Be less efficient
A common misconception is that doubling the transmitter power will give you double the range. This is not true, doubling the transmitter power will only give you 1.414 times longer range (The square root of 2 or 3dB). The best choise in my oppinion is to use a smaller transmitter and a patch antenna (more about antennas later on) on the receiver to get extra range as you normally won’t fly 360° around yourself.
There is no use in having trice the range on your video link than on your RC link. These are my suggestions if you use a standard RC link:
~300mW 1.3GHz / 900MHz transmitter
or a
~500mW 2.4GHz / 5.8GHz transmitter
Plus a ~9dBi Patch antenna for the receiver
