Kit-Y 2.4GHz Directional Antenna

Compact directional antenna for 2.4 GHz networks. Improves the range of your remote control with Zaxcom ZaxNet, Sound Devices NexLink, Phonak Roger systems or any other device operating in the 2.4 GHz band. No ground plane required.

>8 dBi gain: up to twice the range of a standard 2 dBi whip antenna.
Compact and lightweight: mounts on any support and needs no ground plane.
SMA female connector, 50 Ω, up to 10 W.

Compact directional antenna

Description

Remotely position your KIT-Y antenna to achieve better coverage of your 2.4 GHz networks. This antenna does not require a ground plane to function properly. Unlike whip antennas, you can separate it from your equipment’s chassis and place it wherever is most convenient for you. This way, you can overcome obstacles such as buildings or corners, or simply raise it on a mast to gain a better direct line of sight or separate it from sources of RF noise.

It is a directional antenna, so it can help you improve the signal-to-noise ratio of your transmission in critical situations.
It has a very practical and lightweight design, easy to store and transport. It is also made of a highly durable and weather-resistant material.

How to aim it

Reference axes on the Kit-Y antenna

Point the antenna tip (+Z) at the other device. With a 53–70° beam there is no need for fine aiming: a rough orientation is enough.
Linear polarization along the X axis. With the connector pointing down the polarization is vertical, like most stock antennas. Turn it 90° if the other antenna is horizontal.

Radiation pattern

Cuts at 2450 MHz in the E (XZ) and H (YZ) planes. The main lobe points towards the antenna tip, with 17 dB of rear attenuation.

TIP

The signal loss generated by cable extensions in 2.4GHz signals is very noticeable. To avoid losing signal when remotely positioning your antenna, we recommend using very low-loss 50 Ohm cables, such as LMR 240 in their flexible version for on-set use or LMR 400 for fixed installations. You can also compensate for the loss generated by cable extensions by using 2.4GHz amplifiers.
