Signals are easy to optimise with new omnidirectional antennas

L-com has introduced a new line of gooseneck omni antennas that offer a wide range of frequencies and radiation patterns. They are designed for use with unmanned vehicles (drones), video transmission, walkie-talkie communication, manpack radios, surveillance and more.

Gooseneck antennas provide several advantages over conventional fixed-mount antennas. First, they are flexible and versatile. They can be bent and repositioned at any angle, letting users optimise signal reception and transmission. Second, they are durable and made from rugged materials such as fibreglass and metal, which gives them resistance to shock, vibration and other environmental hazards. The third advantage of goosenecks is that they are lightweight and compact, making them easy to transport and deploy in the field.

These antennas cover a wide range of operating frequencies, from 27MHz to 2700MHz. The models are provided in single-band or dual-band frequency options. Choose from single bands of 27, 155, 460 or 2450MHz. Dual-band options are 144/430MHz or 698-960/1710-2700MHz.

These omnidirectional antennas deliver a low VSWR of 1.5:1. This provides minimal power loss due to reflection and high efficiency in transferring power from the transmitter to the antenna.

These new gooseneck antennas have vertical polarisation, an impedance of 50-Ohms, a maximum input power of 10W, and typical gain readings of 3dBi to 5.5dBi. Their connectors are the widely popular SMA male or female.

The gooseneck antennas are 12.4" long and are protected by a thermoplastic elastomer radome. TPE is known for its flexibility, durability and resistance to environmental factors. The antennas are rated to withstand temperatures from -40C to +80C (-40F to +176F).

"These innovative gooseneck antennas provide comprehensive frequency coverage and can be easily positioned for superior reception and transmission," said product line manager Kevin Hietpas. "Their sturdy and compact form factor ensures they are field-ready and reliable."
