Indoor hdtv antennas are perfect for picking up FOX channel and others when living in a large city or within close proximity to the broadcasting towers. However, knowing when to use an indoor or outdoor hd tv antenna, as well as the benefits and the reasons for having one are vitally important when trying to have free HDTV.
There are many types of indoor HDTV antennas, which come in two types, including the HDTVa, the amplified UHF bandwidth version, and HDTVi. Both give excellent reception, but another good option is the TV5 which has an amplified bow tied into it. There are small, affordable and do a good enough job of picking up all the needed basic and local UHF channels.
For those who want improved performance and are willing to give up some needed living room space, the scatter planed SS-3000 is renowned. It provides the ultimate indoor performance, but is still not quite as good as the IMHO antenna.
The designs and types of indoor HDTV antennas include so many styles and sizes with interesting names like log-periodic and yagi, but when it comes down to reception for VHF signals, no indoor antenna can successfully pick them up because the wavelengths are larger and take up a broader expanse of the spectrum of electromagnetic signals. Thus they need to have much larger elements to receive them.
Unfortunately as advanced as the best indoor HDTV antennas may be, the problem of moving signals poses a big problem. It is impossible to line them up with the towers and generally speaking echoes or reflected waves bounce off buildings and walls, making the path to the antenna subject to building construction issues, time, frequency and weather conditions.
