Bester Antenna

What does it isolate? I see the free space between the active disk and the reflector. Give a link to the video.

1800-2100 MHz? What does it mean? Dual band (4g + 3g)? LOL! This is not an antenna, it is piece of... metal. Made very poor quality.

If you use direct cable entry without a connector (or a connector with a solder connection as in the photo), then a spacer is not needed.

What is the polarization of this antenna? Linear? Where are the other graphs (vswr, gain)?

You must get a really strong signal from that station. Its creating standing waves on your antenna.

Congrats on getting the photo orientation right

,,,read this..http://www.antenna-theory.com/definitions/sparameters.php

The port-to-port isolation is defined as the ratio between the power fed into one port of the antenna to the power received at the other port. It is therefore an important parameter to consider if the antenna is to be used with a transmitter that makes use of MIMO. Ideally one would like the two ports to be completely independent (infinite isolation) because then what ever signal is transmitted from one port will not interfere with the signal transmitted from the other port. The lower the isolation, the more interference there will be between the two transmitted signals.

How does that new Bester Antenna behave ,,,???

Hi jomy

somewhere is stated that this type of antenna is circular porized, that is not true at all, i recently have some problems with this antenna 

my son use it on another computer complain to me that he have bad signal, he mean low signal from AP..

after looking i think that something else is wrong ,AP send H polarized wifi signal and when we desolder and solder again coaxial cable inner wire into V

position msignal becomes large and very very good , strenght more than 86%...So people be carefull how you polarize youer antennas!

,,,the truth is that for this type of antenna also called 'gun', the insulation between the ports is not good , so the antenna is not good for MiMo....!!!
