RF Feeder Design

RF feeder

Kintronic Labs uses its own in-house developed CktNet software to assist the network topology design for any type of AM/Medium Wave Antenna Systems optimized for IBOC or DRM digital audio broadcast operation. Initially the associated tower structures are modeled using the Numerical Electromagnetic’s Code (NEC).

The tower operating impedances from the NEC model are then used to develop an RF feeder system design to yield maximally flat common point and associated pattern bandwidth. Any type of tower structure and associated feed mechanism can be modeled.

Following is a response from a Kintronic Labs customer:

“Once unloaded and unpacked, the physical dimensions of the enclosures manufactured by Kintronic Labs were correct to the inch-they fit into the designated spaces like a hand into a glove. Moreover, the gear itself looked too good for the doghouses; the particular circuitry, components, layouts, connections, and ease of access were described only in superlatives by the engineers assembled on site. In a word, it was “elegant.”

After the connections were made to the towers and transmitters, both stations switched over to the new equipment at full power. The only adjustment necessary was to move one tap on a coil to eliminate a small amount of reflected power to our solid state transmitter! A flawless fast installation!”

With regard to Multiplexed Antenna Systems, Kintronic Labs has the capability of modeling the complete Non-Directional or Directional Multiplexed System to yield predictable port-to-port isolation as well as common point and pattern bandwidth. Kintronic Labs has continually refined the CktNet Software as a result of comparison of predicted versus measured antenna system operating parameters.
