Great attic reception

      Comments about RadioShack Outdoor VHF-Hi/UHF Scanner Antenna:

      Excellent reception with an inside the attic mount about 35 feet from ground level. I live in central NH and can now hear Vermont, Maine and Mass Police over 50 miles away.

      Great value and hard to beat for the money.

      The antenna that "can do".

          Comments about RadioShack Outdoor VHF-Hi/UHF Scanner Antenna:

          This is the little antenna that "can do". The Antennacraft ST3 (also sold as the Radio Shack 20-176) outperforms multiple other base and mobile antenna configurations I have tried. Yes, the larger ST2 is noticeably better with a greater range but that antenna is 8½ feet tall and has a massive presence if mounted above the house roofline (it also uses a coaxial cable with F-connecters intended for TV antennas – what's with that?). The ST3 is a mere 19 inches tall and is almost invisible when mounted above a two story house roofline and it terminates to an SO239 connection like a REAL scanner antenna. I have used both antennas (as well as others) and have taken down the monster and I am sticking with the ST3. Its performance is so close that it just isn't worth having the giant sister antenna looming above my house.

          Some reviews point to the radials being flimsy or unsecure. I simply placed two small toothed washers between the base and the nuts securing the radials and they are now rock solid. The antenna stands up to severe thunderstorms with no problems. My ST3 is mounted about six inches above the second floor roofline and is about 20-22 feet above ground level. Here is how it performs:
          • 155 Mhz = I get stations clearly from a distance 45 miles and routinely hear stations up 85 miles away.
          • 460 Mhz = This band has the clearest reception but I only have local stations using that frequency range anymore, so I don't know what the distance will be.
          • Air band = It picks up everything on this frequency range with a solid reception distance of about 100 mile for planes and stations.
          • 800 Mhz = I live only a half mile from a TV/radio stations broadcast antenna farm with multiple antennas including a 1,300 foot tower at 50,000 watts. I can't hook up ANY external antenna to my trunk tracking scanners or I get nothing but bleed over from the towers. Therefore I can't report on the antenna in this frequency range.
          • Trains and Marine = about 45-60 miles.

          If you are looking for an unobtrusive antenna that is a solid performer, this is really the only choice. If you don't mind having a big ugly antenna looming predominately over your house, then the ST2 will add about a 30% improvement on range over the smaller ST3. I should also note that I use a high quality multi coupler to run five receivers off of the single ST3 and it drives all of the radios without any decibel/signal loss. When compared to all antennas out there regardless of size, the ST3 is probably a 4-star but when considering the performance compared to size it's a solid 5-star rating.

          Much improved reception with all my scanners. Cannot expect better for the price. A little heavier construction would be nice, but I really can't complain and enjoy the increased and much clearer reception from long distances

            Comments about RadioShack Outdoor VHF-Hi/UHF Scanner Antenna:

            I was a firefighter and lived on Long Island my whole life. There, you could use a coat hanger and hear the FD and PD with no problem lol. I moved 4 1/2 hrs North to Lake George NY a few years ago and found out a coat hanger just isn't going to cut it. After getting tired of hearing so little with the stock(indoor)antenna that came with the Uniden Bearcat BCT15X, I went old school and put a CB antenna I had in the garage on my roof. Like I said before, on Long Island anything worked. All that did was get me a lot of out of tune transmitting from dispt. I would get the responding units better, but it was more nose then it was worth. I put this antenna up and it made a 100% difference it everything I can hear. Not only is everything crystal clear, but I'm getting other county's around me now that I didn't at all before just as clear as my own county. I don't know how the long run will be as of yet because I have it up a short time. Once this winter is over and I get to the end of the 2014 summer, I'll know better and will update this post if need be.

            Good Antenna for the Price

            Comments about RadioShack Outdoor VHF-Hi/UHF Scanner Antenna:

            Similar to what the specs say, this antenna performs best in the 150-480MHz range. I also noticed improvement in VHF-Lo (around 33 MHz). In the 154MHz range I'm picking up signals from 25-30 miles away that I could not get with the stock antenna. In the 800MHz band the reception is about the same as the stock antenna.

            I have this antenna mounted on my roof and I live near the top of a mountain so I'm using my high terrain as an advantage without needing a mast for this antenna. It was very easy to put together with the included hardware, but the rods seem a bit flimsy so we'll see how well this holds up in the weather.

            One thing that is very important: if you are connecting this antenna to a standard coaxial cable (the kind you use for TV), you will need to purchase a "F to PL-259 adapter" to connect the coax cable to the antenna (Radio Shack item #278-258)

            Comments about RadioShack Outdoor VHF-Hi/UHF Scanner Antenna:

            I was using an ancient directional TV roof antenna to tune in my scanner. I live in NYC and could barely pick up planes even though they're all around me. Being that the antenna was directional, it worked ok when it was pointed at the source but it was unable to pick up much else. But what really made me upgrade was because for the last few weeks, the NOAA weather broadcast for NYC has been down and I was lost without it. I could just barely pick up the NJ one if I went outside with my handheld but I didn't want to have do that every time.

            I looked up outdoor scanner antennas and this seemed like the best one because it was inexpensive, the reviews looked good, and could get it at my local store without having to deal with shipping. So, I went up on the roof and dismantled my decrepit TV antenna but then became a little skeptical because I honestly didn't see how this puny thing would compare to behemoth I just removed.

            Well, boy was I wrong. With this antenna I can now pick up planes over 50 miles away in the pattern at Islip! I can also pick up NOAA from NJ, PA, and upstate NY! I am extremely impressed. I'm planning on buying another one for my parents house.

              I have this antenna hanging upside down in the basement of my house and can reach 2m ham repeaters 20 miles away. Although it appears to be flimsy and could possibly come apart if mounted outside in windy weather it works great if installed indoors.

              Seems like a decent antenna, but check for a short (especially before using to transmit!). Mine had a sliver of metal shorting the antenna to ground. I had it already mounted up on my tower when I discovered it. Took it down and unscrewed the antenna from the ground radial peice and saw the short. Looks like a remnant from manufacuring. See the attached picture of the metal inside the antenna.

              I was also missing 1 of the 3 nuts for securing the ground radials. Now that I have everything straightened out I hope this antenna will last me quite awhile.
