RF Shorts - Aug. 27, 2009

  • • Brian's Brain, the blog from EDN senior technical editor Brian Dipert has tracked his efforts to get reliable ATSC reception. The latest installment, Kitz Technologies' KT-100VG: Robust ATSC Reception Made (Mostly) Easy tracks his experiences with the Kitz Technologies Model KT-100VG Antenna Booster. He has been very happy with its performance. The KT-100VG has a specified noise figure of 1 dB and a 3rd order intercept point (IP3) of greater than +32 dBm.
  • • Eviant has expanded its line-up of portable ATSC DTV sets. The latest model is the Eviant T7 7" digital portable set designed for "school-bound TV viewers." In the press release, the company noted that analog television sets that were used by students earlier this year are now useless. It plugged the Eviant T7 as a "state-of-the-art affordable solution that ensures a steady stream of over-the-air soap operas, reality shows, Saturday morning cartoons, and other educational programs that are enjoyed in dorm rooms across the country."
  • • Elsewhere in this week's RF Report I described Row 44's Internet service to aircraft. KVH is offering a product that provides satellite-based Internet access to leisure boaters and commercial shippers. The company recently expanded coverage to Australian and New Zealand waters. See KVH mini-VSAT Broadband Service Now Available for Australia and New Zealand.
