Hi,

Well they show improvments in the coverage if you use them to enhance the coverage in the direction they send the radio waves.

The standard antennas are tranmitting omnidirectional and the flat one more in the direction of the flat side, plus: They have a higher gain (dbi values) in the reception of your (weak ) client signals.

If you do not see an improvment in transmission, it could be also that the routers power management kicks in and reduces the transmission power.

Did you check the router side reception? This should be cleary improved by the antennas (if they show in the right direction).

With kind regards
Joe

Hi

I finally installed both the ASUS and the DeLock one.

They have definitely made an improvement of 1 bar eception through thick cement with steel.

Just out of curiosity, anyone observed any difference using the directional antennas with the 'explicit beamforming' in the latest firmware?

As I understand it, this aspect tracks / better handles client specific location, so if you're at the end of a long run, explicit beamforming + directional antenna should be an interesting combination.

The firmware has no control over the radiation pattern of the antenna. Transmitters do just not work that way.

I've got a Delock antenna arriving soon but I'm interested in what part of the antenna is actually the directional part, in essence the part you point towards the area you want increased coverage. Is it the outer edge or the flat front?

The flat front/back distribute the waves (the outer edge will have less radiation then the standard antenna).

The radiation is distrusted like this:
HBW (Horizontal Beam Width):
70 @ 2.5 GHz
50 @ 5.7 GHz

VBW (Vertical Beam Width):
70 @ 2.5 GHz
60 @ 5.7 GHz

Where the default antenna has 360 distribution (plus less Gain in reception).

See data sheet for the full details:

With kind regards
Joe
