Bingfu 4G LTE Antenna Mini Soft Whip TS9 (2-Pack) Compatible with Verizon AT&T T-Mobile Sprint 4G LTE Mobile Hotspot MiFi Router Cellular Broadband Modem USB Modem Dongle Adapter

Short:Using the jet pack with the antenna ports butted up against a SINGLE pane window using only ONE of the TS9 antennas gave me an extra 20 MBPS. Before the added antenna, signals was 12 - 25 MBPS. Now it will fluctuate between 20 - 50.Long:Placement of the jet pack is crucial in relation to where the tower signal is coming from. Dual pane windows will reduce signal a lot and so will metal roofs. I placed mine on a little platform between the main door and storm door about 5 feet up from the threshold. The platform is mounted on the main door with the jetpack sitting on top of it. When I close the door, the JetPack antenna ports butt up against the storm door window. I tried adding both of the new TS9 antennas but it didn't make much difference at first. I tried different antenna positions and slightly tilting the jetpack in many directions, but not much happening. Then.... I thought lets just try one TS9 added leaving the other side open. Yup, worked much better. Then I swapped it to the other side and even got better signal. So it worked out for me. I spent several days playing around with it and would imagine this for most cases because everyone's situation is different. Good luck, hope this helps someone else.

These antennae aren’t super powerful or flashy, but they definitely help increase the signal strength and quality. I used them for a dash mounted hotspot on a cross country trip (7 Dec. 2018 through 16 Dec. 2018) and when I’d stop for gas I would take a few minutes to test the speeds without them against with the antenna attached. I often had better results with the antenna attached.I took a few trips between Eugene Oregon and Florence Oregon via highway 126. These antenna enabled me to pick up service during most of the drive except for a mile on the eastern side of the tunnel.They are flexible enough to fit in a Subaru Forestor’s center console with the lid closed. When not in use I kept them in a laptop bag and they did not get damaged from bends or strange positioning.I definitely recommend these for traveling. They gave me just enough of a boost that I remained connected for ~95% of my journey.I live in a high population city with solid coverage by the main 4 carriers. The antenna don’t seem to make much of a difference, but I didn’t expect them to do as much at home as on the road and in more rural areas.

It is nice looking. And it fits the jacks without using adapters, which one might think would would optimize the signal strength. But it doesn't. At least, not on the Netgear MR6500 hotspot.I realize that it would be difficult to say what it would work on, because there are so many variables. Which carrier? And which band will the device be using during actual testing? I tested on the Verizon network. The MR6500 can do virtually all current bands, and I saw it switch between 4G and 5G modes and bands multiple times, so it is impossible to be entirely scientific, but I think it's fair to say that it is always trying to find the best combination at any given point in time.With the internal antennas, LTE RSRP was around -100 dBm. 5G RSRP was typically around -106 dBm. With the external antennas, those numbers were more like -108 dBm and -113 dBm. These numbers varied from one moment to the next, but the speed test results were consistently worse with the external antennas. For example 41.7 / 1.40 with the external antennas and 139 / 5.05 with the internal antennas.I had the impression that the external antennas made the 5G signal strength so low that the hotspot would choose to stay on LTE, which might explain the magnitude of the difference. Again, there was a lot of stuff going on that was not user controllable, so your mileage may vary. For example, maybe some hotspots are limited to bands for which the external antennas happen to be resonant. The antennas measure about 6-5/8 inches above the right-angle connectors, so it would be just about a quarter wave on 430 MHz, a half-wave on 860 MHz, and a full-wave on 1720 MHz.As it just so happens, LTE bands 4, 66 and 70 are on 1700 MHz, so maybe they were hoping for a full wave on those bands. Bands 5, 18, 19, and 26 are on 850 MHz, so maybe they were hoping for half wave on those bands. These antennas have no coils or anything else that would allow them to be resonant on anything other than their fundamental resonant frequencies, so logically, they wouldn't work well on bands that are not on frequencies that are multiples of their inherent resonant frequencies.But just because an antenna is resonant, that doesn't mean that it will have a favorable pattern. For example, it is possible to end-feed a half-wave antenna, but unless that were to happen as a result of the hotspot design, these antennas would function best as quarter-wave antennas, which would have a relatively high radiation angle, at negative gain relative to a half-wave antenna, and perhaps 1 dB of gain over an isotropic radiator. (1dBi) That would be true if there were 4G or 5G bands on 430 MHz, but as far as I know, the lowest 5G band is 77, on 600 MHz.Anyway, that's a lot to say that it seems like it wouldn't work very well, and in actual fact, it doesn't work very well. Which is unfortunate, because the form factor is really nice.

Just added this to my Verizon jet pack. It was running at 4.5 to a high of 7 mbps. It bumped up to 7 to 9 mbps. Not an amazing increase but definitely added some speed.

Trying to get WiFi signal, I must be in a bad location

Purchased these 4G antennas for my Netgear cell modem, but find the modem has a stronger signal without the antennas attached. During testing, I broke the connector on one antenna, ordered replacements before I realized I probably didn't need these at all. But they are inexpensive and who knows, maybe will need them in some situation.

Just one step increase, because here really heavy rural area...not bad.

As soon as they got here I powered down my AT&T Unite 770S MiFi, and installed them. Once powered up I immediately saw a boost in 4G LTE signal. It used to have one bar sitting on my headboard and now it has three bars with these antennae attached. My roku seems to have an improved streaming quality as well so I think my internet speeds have been boosted by the better cellular connectivity. Very good product for the price. Just make sure the frequencies in the product description are in the range that is used in your area.
