## Description

Product description Proxicast 9/11 dBi Ultra Broadband LPDA High Gain Antenna for 4G / 5G / Wi-Fi / CBRS / Public Safety Proxicast's ultra wide-band log-periodic dipole array directional antenna is compatible with all 4G/LTE and Sub-6 5G data services from Verizon, AT&T, T-Mobile, US Cellular, Bell Mobility, Rogers, Telus and many other cellular operators. It can also be used with 3.5-3.7 GHz CBRS, 4.9 GHz Public Safety Band radios, 2.4 & 5.8 GHz Wi-Fi access points and unlicensed 900 MHz systems. This small, light-weight, easy-to-install directional antenna improves transmit and receive signals across a wide frequency spectrum range and is ideal for many outdoor applications, including building rooftops, utility poles, surveillance trailers, well sites, remote telemetry units, meters, homes and offices. With the appropriate adapter cable (not included), this antenna is compatible with USB cellular modems, MiFi Hotspots and routers from companies such as Cisco, Cradlepoint, Digi, MoFi, Pepwave, Proxicast, and Sierra. It is also compatible with most signal booster/amplifiers. Directional antennas must be pointed toward a cell tower. For help locating your nearest tower, consult the OpenSignal or CellReception sites. For MIMO applications mount 2 identical LPDA antennas at 90 degree angles to each other. Not for use with cell phones. Electrical Properties Mechanical Properties You May Also Need Coax is Critical The wrong cabling can wipe out antenna gain. Use only low-loss 50 Ohm coax designed for high frequency applications like our ANT-140-020 series available in multiple pre-made lengths. Water is the Enemy If moisture gets into the cabling it can create intermittent shorts and permanent damage. Seal all outdoor connections with our ANT-900-002 Pro-Grade Coax Silicone Sealing Tape. Flexible Mounting Proxicast's Universal Articulated Antenna Mounting Bracket ( ANT-810-AWB ) provides more flexibility in mounting and positioning directional antennas How to Secure Antenna Pigtails Apply silicone tape to the connector and surrounding coax Create a drip/service loop with the pigtail Secure both sides of the connector coax Secure the pigtail Secure the lead in coax cable For Best Results Mount antenna as high as possible Keep coax leads as short as possible Don't use 75 Ohm coax (RG6, RG59) Don't use a splitter to connect 2 modem ports to the antenna Fully tighten coax connectors to antenna connectors Position away from other antennas, lighting fixtures, motors, Low-E or tinted/coated windows, large metal or concrete objects Stand 3+ feet away from antenna when testing Maximize signal Quality (SINR, RSRQ) not signal Strength (RSSI, RSRP, bars)

Review: Good Product at a good price - I have purchased over a dozen of these antennas for my business. Some are in the field for 5 years now and have worked flawlessly. The plastic cover over the antenna keeps birds, spiders, etc. off of the actual antenna a big plus.
Review: Quality antenna for a backup Internet connection - I decided to set up a backup Internet connection for use during weather related, long term outages of our cable Internet service. Because of the topography of the land around my rural home, we have no useful cellular service with a hand held device such as an iPhone or cellular enabled iPad. My plan was to replace the function of the cable modem with a cellular modem and directional antenna mounted high on the exterior of my home. I purchased a Netgear Nighthawk M1 (MR1100) Mobile Router which offers an Ethernet port to take the place of the cable modem. Since the M1 has 2 MIMO antenna connectors (TS-9), I decided to purchase a pair of these Proxicast 9/11 dBi Ultra Broadband antennas and mount them perpendicular to each other on my mast. Testing involved rotating the antenna mast in the general direction of all the cell towers I knew of, then checking the RSRP and run Speedtest. This M1 Mobile Router promises amazing speeds, but since my antennas don’t see a good signal, my speeds are more on the order of a DSL connection, but I expected that. Curiously, no matter where I pointed the antennas, my M1 always connected to the same Cell ID, with differences in performance depending on the azimuth. I plotted the location of all the nearby cell towers I knew of from a physical survey and then calculated the bearing and distance to each from my home to help with the antenna installation. I made an incorrect assumption that I must be connecting to a tower at bearing 51 degrees, 4.0 km (2.4 miles) because I was influenced by my knowledge of the terrain in that direction. Finally, I used the OpenCellID.org database to find the GPS co-ordinates of the tower I was connecting to and was surprised to find that it was at bearing 147 degrees, 8.25 km (~5 miles). So, back up on the roof and rotate the mast to that bearing. I’m leaving it there as the average of a half dozen speed tests today yields 8.2 Mbps D/L, 1.5 Mbps U/L, average ping 28 msec on ATT Mobile on LTE B 12 (700 MHz). I can live with this performance for emergency situations, especially because it will be accessible throughout my house using my existing WiFi network. Now that I have proved the concept to myself, I intend to replace the Nighthawk M1 with a different cellular router that can be configured for “fail over” as well as run on any US cellular carrier depending on which SIM I use. The Proxicast antennas seem nicely made and I am pleased with them. I did have to modify the supplied brackets to provide clearance when mounting the antennas at the 45 degree angles required for the MIMO installation, however I expected that as well from another review. The brackets supplied were NOT like those in the picture of the MIMO installation. Before I figured out about the true bearing of the LTE cell tower, I had tried the Proxicast panel type MIMO antenna. As it turns out, that may have been a cheaper solution compared to this pair of ultra broadband antennas had I simply aimed it properly.

*by T***M on July 5, 2025*

In my case, the LTE signal sensitivity did not improve. I was a bit disappointed.
