What is Reddit's opinion of Proxicast 6.5~8 dBi 4G/LTE External Magnetic Loaded Coil Antenna Compatible with Cisco, Cradlepoint, Netgear, Pepwave, MoFi, Digi, Sierra & other Routers & Modems with SMA Connectors (ANT-124-SMA-2PK)?

From 3.5 billion Reddit comments

I hate to be the bearer of somewhat trivial news but this antenna will far outperform your unnecessarily huge setup. I have almost every antenna available including the 915 MHz 8 Dbi Rak antennas and these cheap little Proxicast wide ban antennas outperform everything in the omnidirectional category.

I have tried that antenna before... it’s like a 9dbi omnidirectional? Try this one and thank me later ;). You will also need these connectors

If you both put this antenna in your second floor window, you will 💯% witness each other.

You will also need these connectors.
