My neighbor, W6GJB, has a Samlex unit that he says he doesn't hear on 
his antennas, but "doesn't hear" depends on how far antennas are from 
the noise source and what your background noise is.

Samlex makes several models in several series. The "quieter" ones are 
those that carry listing for UL and FCC Part 15 Class B. There are 
models rated for 300W, 600W, and 1kW. Model numbers are PST-300-12 
(300W, 12VDC to 120VAC), PST-600-12, and PST-1000-12. They are all 
listed as "Pure Sine Wave" inverters, and the data sheet says "Low 
interference." Last I looked, I could buy the 300W unit for $148 and the 
600W unit for $224. I don't remember where I priced them.

Don't interpret this as my recommendation -- I'm reading the data sheet 
and telling you W6GJB's experience. :)
