I’ve been in Las Vegas this week for the Amazon re:Invent conference. While there are enough sessions, receptions, and parties to keep you occupied day and night, I just couldn’t pass up a chance to check out the Las Vegas OTA airwaves. The Vdara staff was a bit mystified by my request for the highest south-facing room I could get, but very accommodating. So here I am on the 49th floor with good line-of-sight to the major towers (and a view of the desert instead of the Bellagio fountains, which apparently most people ask for.)
I had packed up a full Entangle development setup, including my trusty Silver Sensor antenna (aka the Zenith ZHDTV1). What I failed to do while busily packing was to check the RF frequencies of the Las Vegas broadcasts. As it turns out there are a few major channels in the VHF bands, including one on channel 2. Sadly the Silver Sensor is a UHF-only antenna.
This brings up an interesting point regarding the current state of OTA antennas: many of them, particularly the compact ones, are UHF-only. Even the ones that claim to be both UHF and VHF don’t handle VHF very well. At best they’ll pull in VHF-Hi. But can you make do with a UHF-only setup?
DVRs revolutionized TV by allowing everyday, non-gadget-oriented people to record shows by simply selecting them from an on-screen guide. You didn’t have to program start time, stop times, and channels by pressing tiny buttons located in the worst possible location of your VCR. Or enter arcane VCR+ codes. With your DVR, you browsed through the guide, found something interesting, and pressed select. Thanks to its program guide data, it knew when that show started and stopped, and which channel it was broadcast on. It even followed time slot changes if the broadcaster decided to shuffle its Sunday lineup.
So I’ve been getting this question a lot over the past several months: Why
