Spectrum Antenna® Spectrum813 Outdoor TV Antenna SP813 Review

It has 40 db gain which is the highest gain we have seen on a large indoor/outdoor tv antenna. This antenna is ideal for people living in rural areas that need a strong antenna to pick up TV stations from up to 150 miles away in ideal conditions. It is also great for people in cities such as Los Angeles/New York that want to get all of the available channels. It picks up weaker stations better than most other antennas.

Best Features
  • Full spectrum of signals - Perhaps the best feature is that it has a wide spectrum of VHF, UHF, and FM signals that it can pick up, from 87.5 to 862MHz. We were able to pick up many hard to get channels with this antenna and it was able to keep a steady crystal clear picture. We are in Los Angeles and usually CBS, ABC, KCAL and Fox are pretty hard to pick up since some are high VHF channels. This antenna has no problem picking up all of those stations and keeping a very steady and solid signal.
  • Longest Range - This antenna has a high gain amplifier to make it 40db gain and the latest UHF/VHF/FM amplification technology so it is able to pick up channels from long range even though it is a compact unit.
  • No Assembly - DIY No professional installation needed. This antenna does not require any assembly. Just snap on the indoor base if you want to use it indoors or put in the mount if you want to mount it on a pole outdoors.
  • Hard durable shell - Another good feature is that it has a hard shell. Many of the long range antennas we have tested are kind of flimsy and not very strong when faced with extreme wind or other weather. This one has a very hard shell so it is able to hold up well in outdoor environments. The elements are also reinforced aluminum so they are very sturdy as well.
  • Works Anywhere In the World - The Spectrum8 works anywhere in the world that uses UHF, VHF, or FM signals.
  • Come with control box that connect to ONE TV.

We tested this antenna in our Arcadia location in the warehouse and was able to pick up 110 channels. Overall we would highly recommend this antenna. It is compact and strong. It can be used indoors in the attic or room since it is not very big. You can also have it mounted outdoors for the best reception.

If you have an analog TV, you will need to get a digital converter box to use this antenna

If you have more than 1 analog TV, you will need to get a digital converter box for each TV. The converter box is the digital tuner that you would use to scan for channels and to change the channel on your TV. So if you have 3 analog TVs and 1 HDTV then you would need 3 converter boxes in addition to this antenna. If you have all HDTVs then you don't need a converter box.

This is the perfect solution for any rural or suburban area because it can pick up signals for up to 150 miles in 1 direction. Directional antennas are more focused so it can go a longer range.

The cost of cable and satellite TV has forced many Americans to turn to free over the air digital HDTV programming. The major broadcast networks such as ABC, NBC, CBS, FOX, PBS and others are broadcasting in high definition nowadays. This means most Americans can enjoy free HDTV programming if they have the right antenna. People who live further away from the broadcast towers should get a more powerful high gain antenna such as the Spectrum8. High gain antennas are more ideal for people living in rural areas that are many miles away from the broadcast towers. During these tough times, every penny counts. Why pay $100/month for cable or satellite if you only watch local broadcasts that are available to you for free over the air? If you are spending $100 a month, you would save $1,200 a year. That is a significant savings. You only have 1 initial investment for the antenna and you can keep using it for free afterwards.
