A Quick Look at WiFi Antennas - Stock v. Hi Gain Vertical vs. Directional

With WiFi- the antenna is everything. It is the interface between the electrical signal on a motherboard, and being thrust out into the air.

Whether it be built in to the wireless access point, a small stubby external antenna, a large replacement antenna with gain, or a directional antenna, the goal is to concentrate the little bit of RF your router can transmit onto the area where all your devices are. Improving the antenna helps BOTH transmission AND reception. It sends your signal in one direction, and it hears better from that same direction.

So that may mean using a flat panel antenna, a vertical with gain, or a directional dish or yagi antenna. A small investment can pay huge dividends in the reliability of your signal.

Higher gain vertical antennas:

Dual Band Yagi:

Small Patch/Panel Antenna:

High Gain Parabolic Antenna:

Thanks for your good explanation.
A question:
For vertical fiberglass antenna frequency 868 mhz for helium, is it better to have a closed circuit or open circuit antenna?
In the case of open circuit antennas, installed on a grounded metal pole, is it still necessary to install light protection?
Thanks

Hi, I wonder, can I use a high gain 18dbi 2.4ghz panel antenna for a dualband Alfa wifi adapter? I cant find any dualband high gain 18dbi 2.4/5.8ghz panel antennas at all

But how wide of an area (width wise) does tha yagi cover?

Interesting video. I wonder if there would be groups of products that you would recommend for certain situations that we could purchase on Amazon.

What can you say about Canopy antenna? Would you also recommend this for WIFI signal boost?

What's the brand and model of that antenna? Trying to expanding the wifi range outside my home.

How about the cable length does it affect the transmit and receive power? what is the best cable length for the 2.4Ghz wifi router using the 9dBi omni antenna? please i need the answer asap, thanks

[ingDemurtas]

what is the difference between a 9 dBi directional and a 9 dBi vertical antenna?

[redumbrella]

the directional antennas would work on two bedroom one floor home?

[jamalamin]

Should have demonstrated the effect on Wi-Fi range

I thought the maximum output power was actually two Watts. At least that's what it was the last time I looked at it. I actually have a machine that can output 2 Watts
