March Meeting: Jampro Antennas and Design Considerations of TV Spectrum Repacking

Broadcast TV antenna manufacturers should make some good sales numbers in the next couple of years as the FCC forces broadcasters to shuffle channels again. This time around, the emphasis will be on broadband designs. Jampro has been working to make their antennas work on multiple channels with minimal wind loading. Many broadcasters will be looking at designs that make the best use of ATSC 3.0 as well. There are things to keep in mind you as broadcast engineers may not have considered, like OFDM Crest Factor and circular polarization for mobile coverage. Jampro logo

As a bonus, they plan to talk about their experience in Singapore with DVB-T2 and Single Frequency Networks.

Join us March 15 at 12 noon at KGTV, 4600 Air Way near I-805 and CA-94 in San Diego for the Chapter 36 regular monthly meeting. Jampro is buying lunch in the cafeteria.

Come on by, and bring a friend.

An attentive crowd at the KFMB studios heard Sumnit Singh make a case for using the technology developed for consumer mobile devices to relay news audio and video to broadcast outlets over private networks. It should be interesting to see if stations step up to the plate to capitalize this evolution, or if an organization will step up to finance the movement and then resell to broadcasters, or if the technology will die on the vine before being rolled out.

Many thanks to Sumit Singh for traveling to San Diego and for buying our lunch. Continue reading January 18 Meeting: LTE for Broadcast by Moseley

November 2016 Meeting: Lawo and the Virtual Radio Station

When broadcasters swap CD’s, cart machines, turntables and audio consoles for PC-based digital playout, mixing & processing systems, we call that Virtual Radio. At our next meeting, guest speaker Bill Bennett, Lawo’s Radio Applications lead in the U.S., will describe virtualization in greater detail by outlining the real applications in use today.  He’ll explore how broadcasters may now reap operational benefits and gains by capitalizing on I.T.’s investment in R&D and will discuss virtualization’s anticipated role in content creation and broadcast workflow in the future.
