Another idea is to build your own portable 6 meter beam. I have found a 2 
element yagi is easy to build, break down and re-assemble quickly. A 2 element 
yagi offers about 3 - 4 dB gain over a dipole. It is easier to put up and take 
down than a 3 el.


I use one for my VHF contest and portable operations. A picture of it is in the 
NCJ March/April 2016 pp. 32. It works... have WAC with it on 6 with 100 W from 
KS on ssb/cw.


A plan for one is here:  http://www.qsl.net/k7yo/6m2Yagi.htm

Hi:

I finally took delivery of a suitable LiPo battery to facilitate "back pack 
portable" operation at the 50 to 100 watt level.   If any of my Canadian 
colleagues are interested I can provide the contact details for a Canadian 
distributor.

At this point I'm planning on simply taking my 50 MHz three element beam apart 
and re assembling it on site.   In my view the beam I have isn't really 
intended for that type of use and I'm curious if anyone knows of any suppliers 
for small 50 MHz beams that break down and re assemble quickly and easily.   
Google searching on my part didn't turn up anything that is currently in 
production.

I'm hoping to shift my focus a bit this year and actually reach the true summit 
of at least one local mountain (vs simply driving most of the way up via 
logging roads.)  Having this ability would also have been useful earlier this 
year when I had to abort my CO81 visit during the sept contest.   In hindsight 
I suspect I could have activated the grid for a few hours on foot.
