&lt;p&gt;&lt;/p&gt;
[quote user=""]So far I have not found any antennas that can handle the depth without becoming permanently damaged by the dive, does anyone have any tips for where I can look for it?[/quote]
&lt;p&gt;As far as I know, we do not have any experience with such a use case. I suggest that you contact antenna manufacturers instead and ask if any of their antennas is suitable for such a use case.&lt;/p&gt;
&lt;p&gt;regards&lt;/p&gt;

The antenna will only transmit data while at the surface.&lt;br /&gt;To ensure I have the antenna far enough over the surface of the water while transmitting it would be the most practical to mount it at the top of the AUV.&lt;br /&gt;&lt;br /&gt;The problem with the antennas I have looked at is that they are crushed by the pressure during the dive, rendering them unusable once the AUV goes up to the surface to transmit data&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
