160 and 80 will be difficult.  Can you get another vertical up about 60 
feet?  You can top load that with a trap for 80 and have "t" wires at 
the top that also act as guy wires.    You can also bottom load for 160 
and maybe that will be good enough for you. Radials whatever you can do 
will help.

An Inverted L with about 50ft of vertical will work ok....If you can 
keep the horizontal end up in the air  around the same height or more.  
It doesn't sound like you have any tall trees to work with.

For receiving I have been very impressed with a K9AP loop.  25 ft up and 
about 15 feet out at the corners.  It does not take up much space and 
you can reverse the direction easily with a relay.  A flag or pennant 
will work too.  You can never have enough rcv or xmit antenna!  HI!

Welcome to the club!
