help me to make a design

34 posts in this topic

Good day 

 

I am from Philippines and hopping that you help me to make a design for an easy made outdoor antenna for my modem huwei b315s-936 with a band 3 (1.8ghz) frequency, with a distance of around 20km to the cell tower.

What STANDARD is this...? LTE , UMTS , or GSM... Sensibility is DIFFERENT on all 3 and WLAN...:|

MAX is UMTS  2100 MHz: -106.7 dBm@3.84 MHz

LTE, UMTS, GSM are supported , but my focus is on LTE BAND 3

23dbm (100...150mw MAX) output UPLOAD

104dbm max Sensitivity DOWNLOAD

Still it looks like you gonna need a parabolic dish...NOT SMALL with more than 20dbi of gain...perfectly pointed and the modem close to the antenna...which should be on the ROOF...IMHO

Thanks Clanon,

That's exactly the frequency.

So if parabolic type is the best antenna for my need, 

Can you help me make low cost one??

the reflector could be something similar to a TL-ANT2424B (tp-link) but about the feeder you gonna have to ask JOMY (admin)

I'm inclined to at least 1m2 of area and the most "perfect" parabolic or cylindrical curve...possible...(Cylindrical is much easier to get)...but the KEY ..is the feeder efficiency.

We should adjust it for dielectric PVC for sure (DOME) and test it on a parabolic dish...

(PS: i could give it a try if you want..) My CST is 2017...can't open new files...

Nice one Admin ??

thanks for your effort. 

I'll try to make this one.
