LMO6138-WB-SMSM - 5G/4G/LTE Multiband MIMO Outdoor Omni antenna

The LMO6138 is a MIMO (2 port) 5G/ 4G / LTE Multiband omni-directional antenna. Housed in a durable radome, the LMO6138 antenna is suitable for outdoor applications including leisure marine environments to improve reception of 5G, 4G (LTE), 3G and GSM signals.

The frequencies supported start at 617 MHz and cover 600, 700, 800, 900, 1800, 1900, 2100, 2600 and 3600 MHz covering the majority of 5G, 4G, LTE, GSM and 3G frequency bands.

Ideal for both fixed and mobile 4G and 5 deployments such as wireless CCTV and security, 5G and 4G Access, monitoring systems, industrial wireless and leisure marine, the LMO6138 offers installation flexibility and combined with RF240 and RF400 cables can offer a customised solution for nearly every application.

The LMO6138 MIMO 4G/5G antenna measures approximately 187mm in height and 106mm at the base. The peak gain on each element is as follows:

Installation FAQs

Where should I install the LMO6138 antenna?

The antenna performs best when mounted outdoors on a pole, wall, or non-metal surface with a clear line of sight to the nearest cell tower. Elevating the antenna usually improves signal strength.

Can the LMO6138 be installed on a metal surface?

While possible, performance may degrade due to reflections and ground-plane effects. It’s best to mount it on non-metal or insulated surfaces.

Does the antenna need to be pointed in a specific direction?

No. The LMO6138 is omni-directional, meaning it receives signals from all directions, this is ideal when you don’t know exactly where your nearest tower is located.

What is the best cable type for connecting the LMO6138 to a 4G or 5G router

Use high-quality, low-loss coaxial cable such as RF240 or RF400, and keep the cable run as short as possible to reduce signal loss.
