Portable repeater for support & rescue antenna

[WRPL862]

I am part of a support and rescue team, we are wanting to build a few mobile repeaters so that we can place them in areas that are very difficult to get signal when doing a rescue or providing support. What would be the preferable antenna to use that would be portable and provide ample range and durability. Our repeaters are in a waterproof case with the battery and exterior connections for the accommodating solar panels.

You ended up with a double post but we have an 8ft pole last that  slides into a 2” hitch and holds a 10’ comet 712 efc antenna.  With a 50w base it radiates 350w.  Puts the tip of the antenna at about 20’ off the ground.  With the set up on a hill we can do big milage
