I have used the Austin Sprectra antenna for 16 years. Trunk lid motorola mount. I had used mobile scanner antennas by Antenna Specialest, Radio Shack and others but the Spectra with the tuneable tip for low band has worked the best. Yes pricey but for 16 years, its a minor costs per year. Good stainless steel, no rust, coax has held up. The signals received appear to stay up for a longer time. Low band is not a big deal now, but in the 70's thru early 2000's, low band was the system of most highway patrols. On 800 mhz, I used it to monitor all the companies 800 mhz trunking sites, all over the eastern and southern states. Never failed to acquire good reception. If you were looking for a first scanner mobile antenna, get the Sprectra and it will be your last antenna. For my HT's, I use ther Condor. Same good results. Oh, you sample other antennas, or play with home brew stuff, but I always return to the Austin products.
