Title: Is 2.4Ghz for Boat different?
Post by: Rooster on April 28, 2012, 02:33:27 PM
Had following queries on the 2.4 Ghz radio for Boats,experts please advise
1) Are 2.4 Ghz radios for Boats any different than that for planes? Would a Turnigy 2.4 9x  work for Boats as well.
2) Does 2.4 Ghz produce glitches due to reflection of signals on water? ( Heard this somewhere)
3) Can 2.4 ghz work without glitches, when RX antenna is completly inside the hull?

Shreekant

yes u can use turnigy 2.4 ghz 9x radio system on boat
i don't think glitches will be there because one person from Bangalore used my set flysky th9x 2.4 ghz radio system to his ship
it was to working without any glitches

I've used 2.4Ghz for all my Hovercraft over water without any glitches at all. Antenna was also enclosed within the cabin.

Sree.. all radios are similar..you can use 2.4 to 3 GHz anywhere you like.. but take a little care while using over salt water source.. but it will make head aches when you tries under water.. to avoid any signal loss you can fix the antena of your RX in 90 defree.. and please keep the antenna of TX parellel.. a simple aluminum dish also helps to increase the effective range.. above mentioned radio will give you a good effective range far beyond imagination..  :thumbsup:

Low-frequency radio waves (AM/FM radio) travel easily through brick and stone and VLF (Very Low Frequency) even penetrates sea-water. As the frequency rises, absorption effects become more important. However this is significant in practical life only in 50 GHz and above.
So AFAIK a 2.4 Ghz would not have any glitches even  near sea water as there would be no loss of signal (WAVE ENERGY) due to absorption by the surrounding that may cause glitches.

I may be wrong,but i supplied all that was known to me.
