Stubs are not nearly narrow enough to solve this problem. The unit in 
question is in clear violation of FCC Rules if it interferes with 
licensed communications, including yours. If it's putting out that much 
signal, it's clearly in excess of FCC Rules, probably wildly so.

A year or two ago, I bought a low power FM TX on amazon that I hoped to 
use to feed an internet radio RX around my rural home and yard. I 
quickly rejected it -- it produced a ton of RF trash up and down the 
band and lots of audible distortion on its TX frequency. As I recall, it 
was advertised as 1W, and I had a 20 dB pad on the antenna. For at least 
five years, I've used a legal "trucker's" FM modulator that is in the 
10mW range; my goal was to get about 6dB more field strength, and a 
cleaner signal.

W4TV has given you good advice on the route through the FCC, but buying 
them a decent unit may be the more practical solution.
