      Comments about RadioShack Magnet-mount mobile scanner antenna:

      I use this with a BCD536HP as a base station mount. I have a metal roof and just took it up there and the magnet holds it solid. I pick up signals clear and strong out to almost 100 miles. I live in a valley so that was surprising. Clear signals for railroads, EMS/Fire and Statewide LE P25 systems. Will get another one for a mobile mount.

          Comments about RadioShack Magnet-mount mobile scanner antenna:

          I got this for its intended use: a mobile scanner antenna. It performs quite well. It was pulling in stations as well as the vertical dipole antenna I have on my house. It works well on VHF-High, UHF and 800 MHz. I measured its impedance with an antenna analyzer and I got the best SWR measurements of 1.0:1 at 157.000 Mhz on VHF-High and 1.3:1 at 445.000 MHz for UHF. For VHF-Low, forget it; I got a SWR value of 27:1 at 40.000 MHz. The SWR improved slightly as I decreased the frequency but was still very poor. But, VHF-Low is all but forgotten these days so not that important really. I did not attempt to transmit with it, I think it is designed for receiving only. I drove with it at highway speed and seems solid up on the roof. Overall, a good antenna for mobile scanner reception.

                Bought this antenna in hopes of getting better reception on a 800MHz trunked system of my local police dept. Made it worse. DO NOT BUY FOR 800MHz.

                Ham radio users: Only 25 watts on 2m, 440, 6m. Ok for maybe handhelds, but do not use on your expensive mobile rigs!

                Overall, this is a good scanner antenna, but it is very flimsy made, and is easy to break and fall apart. I have owned two in the past 15 years, and they are only good as an emergency antenna until you can order a better made ham radio antenna.

                  This antenna is great. I stream a live feed from my home with a handheld scanner. I get better reception with this antenna than from any of the others ive had.

                    i bought this based on the reviews i read. i live in southern California. i wanted to hear more. i set it uip in my home with no grounding and started to hear more on my scanner. i was hearing things my whip didnt pick up. all were local though. before all i could hear was dispatch now im hearing emt, south county fire. its better than the whip antenna that comes with the scanner but not as good as what other people have said. yes i put in an L bracket on the outside of my house at the roof and stuck it there. it wasnt any different than inside my home. if you want 50 miles then get a 50 mile antenna, if you want better local coverage than this will improve your signal. i get neighboring cities which are 10 miles

                      i have been using this product for about 2 years now and it is great because gets great reception, and it is not expensive. I am a volunteer firefighter and i use it for my fire/ police radio in my vehicle and I am able to communicate with other fire and police departments when i am out on a 911 call. for me to rely on this product when I am out on a 911 call must make this a very durable, and reliable mobile scanner antenna, and it great for VHF, UHF, FRS, GMRS, PMRS, POLICE, FIRE, and EMS radios, and scanners.

                        Comments about RadioShack Magnet-mount mobile scanner antenna:

                        I had this antenna for over a decade. It has traveled thousands of miles on top of three vehicles with no problem, even when getting knocked off in parking garages. I used it mostly for scanning reception, then alternately for 2M/440 amateur radio transmission. I recently took it in my shack and mounted it on top of a metal file cabinet, then hooked up an antenna analyzer. This antenna resonates on 6M, 2M, and 440M with SWR <1.5:1 on all three bands. Now I have it hooked up to my HF rig for 6M digital work and it still works great! I might buy another one just to have around, because this antenna is truly sturdy and versatile. While this is rated for 25-1300Mhz, I also use it with an AOR8200 to pick up shortwave with decent results.

                        Summary: Sturdy, versatile, great value.

                            I've had this antenna (actually 2) for over 10 years. Monitoring all bands is great! It works great for mobile and in the attic! Don't tinker with it and it will work great. It must be on solid metal for good grounding. Cars now-a-days, you may need to convert it into a mounted antenna.
