That antenna is practically useless.
What band are you currently connected to?
Buy an antenna that is tuned to that frequency more-so than others.
And what is your surroundings like? if your in the city, sure a panel should be the way to go, but if you are relying on signals bouncing off buildings, you would be better off with 2 separate omni antennas, just like your cellphone uses.
For example, when I take my phone along a road with buildings on one side, and the cell tower is off to the other side a long distance away, the signal is best when im in front of those buildings, because the buildings act like a dish reflector and help with the signal. If you have a directional antenna which is pointed away from those buildings towards the cell tower, you will miss out on the benefits those buildings actually bring to you,, and spending money on a device to bring about such a problem is a mistake.
S if you'd like, post an image of your surroundings and whatever you have, and ill look into the best antenna for you..

Thanks for the advise sir.

depends where you are.
BUt usually, if u have decent signal from teh tower, Band 41 should provide the best download, but Band 28 should actually provide the best upload.
Why...
Band 28 is a low frequency (700 mhz) has a lower capacity but travels further.
band 41 is a high frequency and also has a large capacity of about 20 mhz (only 20 mhz in use for your globe at home)
Up high at this frequency, the signal fades away much sooner than a lower frequency, however the powerful tower transmitter is able to broadcast it loudly and therfore it is great for downloads.
Your home device however is not as powerful and therefor the strength of the signal it sends is not as strong to begin with, so it fades away much faster on the way to the tower. So uploading (sending data from your home device) is often much faster at a lower frequency, because the lower frequency is easier for your little device to transmit.
Further to that, the band 28 (700 mhz FDD) has its own reserved Frequency channel for uplink (upload) whereas band 41 (2600 mhz TDD) uses timingof up and downlink data on the same channel so ifthere are lots of people downloading on your sector on B41, your uload speed will be affected by them.
Ive found if i need to do a Skype call, im best using B28 (so that my phone can upload video data), but if im downloading something or browsing, I leave it on B41.
Band 41 is not available everywhere, so you may be limited to B3 or B28. If thats the case, you jut try both and see. If your in a densely populated area, chances are everyones cellphones are on facebook hammering band 3 (1800 mhz) and it would be unusable.

3 km away from the tower with band 3 and 28 and many trees from my house to the tower. What's the best antenna?That antenna is practically useless.
What band are you currently connected to?
Buy an antenna that is tuned to that frequency more-so than others.
And what is your surroundings like? if your in the city, sure a panel should be the way to go, but if you are relying on signals bouncing off buildings, you would be better off with 2 separate omni antennas, just like your cellphone uses.
