5/8 Wavelength: $20. Stacked 5/8 over 1/4 Wavelength $25. Local pickup only please. It just isn't worth shipping these. The 5/8 Wavelength is a Hustler 'Buck Buster'. The stacked 5/8 over 1/4 is a GAM Electronics product and had better performance than a CG-144 in a side-by-side comparison. The magnet on this antenna is too small for an auto roof, and I used it as an indoor antenna on a ground plane. If you wanted to use this mobile, you'd need a different mounting arrangement.
