Since a new tower had been erected in 1997 with HDTV in mind, it already featured a broadband RFS panel antenna used to broadcast the analog channel 29 and was capable of accommodating the future DTV channel on UHF 15. The trick after expanding the building and installing the HDTV transmitter was to combine the [...]
For this facility (KHOG) the gain of the antenna was considerable so that only about 10kW TPO would be needed to meet the maximized ERP level, so the choice of a solid-state Diamond transmitter from Harris was made. The benefits of this choice were that the multiple modules and power supplies allowed for considerable [...]
Here is a project I am justifiably proud of. Our corporate engineering management had determined that we were to use a Harris Flexicoder as the core of our HDTV encoding, but outside of that we were to determine what we needed to best integrate it into our facility. Initially, I was not pleased with [...]
A few grainy images of the Andrew side-mounted antenna we ordered for the KHBS DTV transmitter in Poteau, Oklahoma (which serves the Fort Smith, Arkansas market).
Because there was simply no room on the existing tower to place a DTV antenna that would be even marginally effective, I was successful in convincing the company of the need to build the tower and locate the new antenna on it.
I’d love to take all the credit for this project, but who would believe me?!?! This required the experience and assistance of not only our station’s engineering department, but also the combined efforts of contracted electricians, transmitter installers, HVAC installers, a local construction company and tower riggers.
Prior to installing the coming DTV transmitters there had to be a manner in which to get the HD signal to the transmitter. Since we would ultimately have two high-power DTV transmitter sites and they are a considerable distance from the studios, the only practical solution would be to encode the HD signal at [...]
In order to accommodate the additional transmitter equipment for this station’s HDTV transmitter the building had to be expanded considerably. I was able to include in the budget enough area for a sound-resistant office where maintenance records, spare parts and test equipment could be kept and calls could be made without having to shout over [...]
