The obvious question is that if you only have to go 50ft, why not just
run 50ft of CAT5 ethernet cable to the back porch instead of 25ft of
coax cable to the attic?

25ft of coax cable is not all that lossy. The two available types are
LMR240 (about 1/4" diameter) and LMR400 (about .410" diameter). Losses
for 25ft would be about 4.3dB and 2.0dB respectively. At 50ft range,
either coax will work.

See:

for pre-cut and connectorized pieces.

I'm not sure exactly what to recommend for an antenna. If all you
have to cover is the back porch, then some kind of directional panel
antenna will be the cheapest and easiest to install. If you have to
also cover the entire house, an omnidirectional antenna might work
best. Hard to tell from here.
