What is the best amplifier ?

I bought a RB433AH+R52Hn+2*TL-ANT2408C.
My problem is these device and equipments don’t ship my requests, mean converged area is not fit to my need.
I want to buy amplifier(s) to use only one radio and install antennas at the far place about 15m distance between.
What is the best solution for me?

Best Regards

what distance do you get now? your antenna is only 8dBi, so the problem is not the amplification, but the poor gain of the antenna. amplifier will only make the situation worse, it will amplify noise.

I want only install antennas far from the radio to coverage the bigger area.
If install one of the antenna near the radio and another far from the radio, about 15 meters, then the supported area is larger than all of antennas install near the radio.

How can I do this idea?
What equipments are need?
Amplifier/Repeater/… which I need?

Correct me if I am wrong…


You are trying to connect several sector antennas to a single radio?
If this is true use a signal splitter.
If you use a signal 2 output splitter the output power is dropped by 3db on each output.
a 3way is about 4.5db loss, adn a 4way is 6 db loss.

so if you are using 8db antennas through a 4 way splitter the relative power of each antenna is equivalent to 2db.
So Normis is correct on that part… You WILL need larger sector antennas if you use a splitter.

Optimally you should use seperate radios to each sector.
by the time you run your Coax and crim ends, splitter etc. the costs go up.

BTW. Do yourself a favor, and use proper sector antennas.

Thank you tgrand,

I want use several Omni-Directional (8db or above) antennas connect to same radio, but at different places and different distances from radio.
But if sector antenna is better tell me, please.
The plan as picture bellow, the picture is one-floor but my building is 4-floor.
At the end please help me to select devices that need lower radio need to install WLAN at the building.
