What are you using for the "other half" of the antenna? A quarter wave length of wire is only half an antenna.

Subject: [Antennas] Affect of trees on quarter wave wire antenna.
Hi
 I have a limited space to put a 75 meter antenna. So, I decided the best option is to run a quarter wave wire. In theory the principal of a quarter wave is simple. How ever I am having no luck getting the SWR down to one to one. Currently I am sitting at 7.8 to one and it gets worse toward the bottom of the band. This would indicate that the antenna is to short. I am wondering however, if some if this is caused by my having to run the wire through the trees and the trees causing some type of interference? Do I just need to buy an entire new run of wire and start over?
God bless,
Mark
