This is one of the lightest and slimmest antennas on the market – Suitable for the 900 MHz ISM band. It is designed to operate in free space, or stuck onto a relatively RF transparent material, eg. Foam wing, fuselage, balsa wing, thin fiberglass (not carbon fiber).

It has better than -10dB return loss when in free space, to stuck on a thick slab of EPP foam so it quite insensitive to the installation.

To use this bare antenna – a good quality coaxial cable needs to be soldered on the feed point

We have several pre-stripped RG316 cables at a few lengths to make installation easier, you can also use one of our RPSMA extension cables cut to your desired length.

Flex 1

Use of this antenna is easy, as it has integrated feed point matching, an integrated balun for feed cable isolation and black solder resist with gold plated pads for soldering.
