The FREEDOM+ Surf system has been designed to fit nearly all surf board sizes, both short and long boards, and is suitable for all levels of surfing performance, with the sticker thin antenna having zero impact on your boards performance.
There are 2 x Tail Pad / Antennas available and the one you use, will depend on your surfboard size and desired level of protection. Please note that it is only the Antenna and Electrode part of the product that is different. The Tail Pad is exactly the same for each product and both use the same FREEDOM+ Surf Transferable Power Module which is housed in the kicker of the Tail Pad.
The adhesive antennas in both the Tail Pad / Antenna and Tail Pad / Antenna - SHORTBOARD, will fit any board where the tail width of a board, measured about 25 mm (1 inch) forward of the most forward fin, is between 420 mm (16.5”) and 480 mm (18.89) with a board thickness of no more than 25 mm (1 inch). This covers 95% of boards.
Long boards with a fin box do not cause consideration because the position of the tail pad which does not end up right at the back of the board like a short board, although this is not much of an issue on a long board. Attached are two photo's showing the decal laid out before installing on a 9'1" Mc Tavish long board and you can see it positions quite well. The electrodes not being in the centre does not matter given your usually located towards the back of the board when paddling and sitting, in the protective area of the electrical field.
The Tail Pad / Antenna has not generally been designed for SUP. However, it may be possible to install it on some SUP boards, noting that because of the restrictions above, the Decal Antenna may not end up in the centre of the boards underside because of SUP boards width and thickness, compared to a standard surfboard. The bigger issue is that most SUP's already have a tail pad in place, but take a look at the attached solutions our customers have come up with.
For the installation on a SUP you may need to consider the reverse of the install on a surfboard - so install / position the tail pad first, then roll around the rail, then apply the antenna, which as stated will not end up centred. We suggest trying this method before removing the adhesive to ensure it will fit.
