hi Nelson,

yes, it is a lot of work, you could just attach the magmount
to any metal object, patio table, metal railing or window a/c unit, etc.

or for a few dollars and less work build a great 2m antenna
using #12 thhn wire and a few feet of pvc pipe.

this is the half square, works great, it is directional.

then you can try this one, the Moxon for 2m, little harder to make
but has similar gain to a 2 element yagi in less space and direct fed
with 50 ohm coax (like the half square is fed).
