Hi there!
I have purchased a patch antenna too get a better signal for my RC radio transmitter.
The radio is selectable for transmitting and receiving either on 2.4 or 5.8
My new patch antenna can transmit and receive at both 2.4 and 5.8 GHZ
I have a picture of what the inside of the antenna looks like. My radio has two antennas. Both rated for 2.4 and 5.8
My question is: are the two antennas inside this unit dual frequency each or are they wide band each, that covers from 2.4 to 5.8?
The Antenna is called 4Hawks Raptor SR





Thanks
Glen

 

Few Antenna designs are actually "Broad-Band",
( Disk-Cone, Helical, and Long-Wire, Antennas are examples of "Broad-Band" Antennas ).
especially Printed-Circuit-Antennas which usually operate
based on a special set of rules not usually used in "conventional" Antenna designs.

Both of the Antennas are "Dual-Band" Antennas.
This means that they "Resonate" best near 2 different Frequency-Ranges,
which are usually even multiples of each other.

Using 2 Elements tends to make the Antenna more directional than it would be if only using 1.

Thanks for you for your response LowQCab, much appreciated!
I have found that this new patch antenna has boosted my signal strength and quality of signal compared to the original two Omni directional antennas that came with the radio.
I placed two 5.8 passive Yagi antennas Infront of the Patch antenna and achieved even more signal strength and quality. My next question is should I remove the Yagi's reflectors, seeing as they are not mounted behind the patch antenna? Or are the reflectors still of use even thought they are up front of the patch?




Thanks

I'm surprised that the Yagi's didn't cause problems.
The supposed "improvement" is probably all in your head.
If there was any improvement at all, it is at the expense of coverage area, ALWAYS.
That's just how Antennas work.

Using 5.8-Ghz "only" will allow You to use much smaller Antennas,
with the only drawback being slightly less range when behind Trees,
or other large physical-obstructions.

I would recommend using 2 TBS-Triumph-Pro Antennas on your Transmitter,
and a single, matching one on your Quad.
THE ANTENNAS MUST BE A MATCHING SET.
The 2 Antennas on your Transmitter should be positioned 90-degrees apart for best results.
They are extremely good at rejecting outside-interference.
The Antenna on the Quad should be vertical, but tilted-back about ~30-degrees,
so that it is roughly vertical when flying forward.
