I think there's something wrong with that model if you're getting such a low Z. 30 ohms is more like it. However, there's a cure...

Dunno how clever this is, but for years I've used a simple coax-fed homebrew 80-40 trap dipole/inverted V. Same size as a G5RV. Traps are made from PVC pipe and coax, per N4UU article in QST (December 1981, I think). Need a dipper and a SWR meter to set up the antenna. Works really well on 80/40, can do other bands with a tuner. 

In the past two years CW SS's I used this antenna with the peak at 35 feet. Worked over 300 contacts and over 70 sections each year in Q class with my K2, and neither year was an all-out effort.
