I agree with John and Clarence. You're going to have a difficult time
going through two adobe walls. I help maintain a radio site with an
attached private residence. The house is adobe walls and tile roof.
The wireless access point is in the radio site. All attempts to get
coverage inside the house have failed miserably. The adobe acts like
a brick wall. Hell, it is a brick wall. You may find it necessary to
use some other method of connection. At 75ft, you could probably run
outdoor gel filled CAT5 cable. If there's a common power or phone
line, look into those:

Also CATV:

I'm not a big fan of Hyperlink Tech but they do have a good assortment
of goodies. Fab-Corp is a good supplier.

I'm not going to recommend a specific antenna type or model without
some additional guesswork. Take the radios you currently own, with
the stock antennas and try "drilling" through the adobe walls. If you
get any kind of signal, grab some signal strength numbers. If
possible, give an estimate of how many more dB of signal you need to
establish a reliable connection. I suggest using Netstumbler on the
client end to an access point on the other. Offhand, I don't think
it's going to work unless you have common windows through the adobe.
Think line of sight.
