WiFi/LTE antenna BDM-2

,,,mitiche...please tell me how you posted the images above...!!!???

make sure there's GOOD electric contact between inner wire and Excited Disc (that White looks like polyester resin or some dielectric paint)

withe antenna without antenna 

hello sir i didn't get a good result its the same result with or without antenna 

im using the 1800 model and i think my aria is using band 40 

can i make changes to the antenna to get a batter result or maybe im bot using it correctly ? 

i have a TOPLINK model : HW593Pro it hase 4 antennas and im usin the last one from the left side

yes i scratched it off

,,,pay attention to the connections to both the antenna and the router...!!!

,,,what kind of connector did you use here...???

 

[mitiche 12]

 the connector i used is from a tv receiver

and  about the soldering it didn't stick to the aluminium so i solder the cable from both ends ands 

should i use another metal for this ? 

and what about the dimensions i found out that my region is using a 40 band 2300 Mhz 

should i cut it to be like the first model?

Your connector is not good, change it.,,,same with the router connection....!!!!

BRASS is great...Copper would be BETTER...(signal is LOST on small little defects on the way from Wireless card trough the antenna final contact point) CONTACT should be FIXED no play...

LTE Band 40 uses the 2300 MHz to 2400 MHz frequency range (FIRST the FREQUENCY then the BUILD around SUCH frequency) you seem to be getting NO SIGNAL 2 db is nothing

mitiche...try this,,,,

mitiche...try this,,,,

if the connection is TOO BAD (75 ohms cable on wrong connectors , bad contact impedance high VSWR) it might be switchin to INTERNAL ANTENNA...hence 1-2 dbi gain

okay sir im getting Busy this week ill try this next week thank you for your help

router no support externel antennas

Your problem is with these two connections....

All LTE BS have X-pol polarization, according to open sources.
Explain why the receiving MIMO antennas are still all set to X- polarization.

So I think you should have two connectors on the antenna.
