An Introduction to the Embedded Antenna Design (EAD) LCO7270 Multiband Omni Antenna

Monday, September 29, 2014

Embedded Antenna Design (EAD) recently announced the LCO7270, a groundplane independent 4G/LTE multiband omni antenna covering 690-2700 MHz i.e. 4G, LTE, 3G and GSM/Cellular frequencies.

Housed in a weatherproof Luran sheath with a passivated aluminium base, the LCO7270 is groundplane independent and doesn’t need a metal surface to operate effectively. With gain of 2 dBi across the bands, the radiation pattern is omni-directional making it suitable for both fixed and mobile applications.

Unlike other compact omni antennas that require a groundplane, the LCO7270’s ability to be mounted in free space or on non-metal surfaces and enclosures is a tangible advantage. The antenna can be fitted with a number of connectors including N-Female Bulkhead (for stud mounting where a smaller mounting hole is required or where there is less real estate inside the enclosure), N-Male, TNC-Male, RP-TNC, SMA, and RP-SMA. There is also an option for a wall-mount version using a stainless steel L-Bracket.

Initial samples will be available by the end of September and production orders are expected to start being fulfilled by the end of the second week in October.
