Welcome to the unfashionable end of SOTA 
There are many ways to get on 2m SSB portable and lightwieght… Normal is to mount something on a fishing pole to get the extra height.
Something akin to 2M Foldable moxon or the similar Lightweight 2M antenna
A small 3 element bean also works well and I have had good results from a 3 element delta quad similar to 3 element Delta Quad. I have a lightweight one that can be mounted on a camera tripod and works very well.
I dont think we will make it across the pond though although having said that using the arrow handheld dual band 2m/70cm could work via satellites.
Have fun
