ABONIX 4G LTE Omni External Antenna 12 dBi with LMR 300 Cable 15 Meter & Splitter Splitter Cable SMA Female to Dual SMA Male (for TP-Link Routers)

Works great for signal booster for 4g modem

Using it for more than 15 days. It's very much stabilize my router speed and ping. Before installing it my ping is more than 50ms (sometimes its exceed 100ms) and speed is very slow at day. After installing it, ping got stabilize between 15 to 19 ms (max 25ms) and speed at day is 15-19 mbps. My airtel local area avg speed is 30mbps both download and upload. Well I getting almost avg.

It does not work properly, do not buy it, otherwise your money will be wasted

Very best item. very good network coverage

It's working well but not those much how much I speacted.Not capturing strong signal but in my area there is very strong coverage but still antenna just captured only medium signalMy phone giving 25 to 30 MBps speed but antenna giving only 15 to 17 MBps speed, I setup it with 20' fit pipe , but not effected

Good working fine

I am now sure that what the seller has uploaded or stated in amazon webpage is a copy paste from a piece of paper that the seller might have received from the Chinese manufacturer.The 12 dB gain is absolutely a false claim.I wish the laws in India would have been more tighter (like that in Canada or Few countries in western Europe), then the seller won't have dared to post such fictitious claims on online market places.What ever little gain that one can achieve with this antenna system (assuming the external antenna is working) goes away due to leakage in the wire.Overall, I would not recommend this product at all.PS. I work with all types of RF cables as part of my job and never came across such a bad quality product.
