Hi Ray, this is Steve, NY3A.
 70ft a side, assuming 4 sides is 280ft total. This antenna length is a half wave on 160m. Loop antennas are normally 1 wavelength long, so what you have is an 80m loop. Not sure if the loop is horizontal or vertical but I'm guessing it's horizontal. 
If you want to use this antenna on 160m, one option is to open it at the middle (140ft point) and try to use it as a dipole that doesn't go in a straight line. Feeding it with open wire line and a tuner instead of coax will save you tuning time and allow you to use it on most other bands. 
A better option, if you are looking for a 160m only antenna, would be to try an inverted L antenna. It will give a lower angle of radiation and be better for DX than a low dipole. On the other hand, if you just want to contact up and down the coast and into the mid-west, maybe occasional dx, a low dipole is good.
