The Elsema 27 Tuned Antenna – ANT27S has been discontinued by Elsema.
The ANT27M was a 1.13 metre long ground independent helical whip antenna with omni-directional radiation pattern of 360 degree coverage.
The term “ground independent” relates to its ability to be completely independent of the need for negative grounding (Earth).
This feature allows the antenna to work efficiently in a wide variety of applications.
It is Retro Remotes recommendation that if you require the above antenna that you upgrade your opener.
Please contact Retro Remotes to arrange a suitable upgrade for your opener.
