The manual for the Drake TV-3300-LP Low Pass Filter provides instructions for installation, emphasizing the importance of maintaining a low SWR in the transmission line and ensuring proper connection to prevent damage. It also covers the filter's operation in preventing spurious outputs and harmonics from affecting TV channels, while noting that some interference issues may require additional high pass filters at the TV receiver.
Manual Overview
The Drake TV-3300-LP Low Pass Filter is designed to prevent spurious outputs and harmonics from interfering with television signals, specifically targeting transmitters operating below 30 MHz. It effectively attenuates harmonics on amateur and CB bands and protects TV channels and intermediate frequencies above 36 MHz. The filter features a design cutoff frequency of 383 MHz and provides attenuation greater than 80 dB above 41 MHz, with minimal insertion loss below 30 MHz. It supports a power capacity of 1000 watts and maintains an impedance of 52 ohms, utilizing UHF type SO-239 connectors. For installation, ensure a low SWR on the transmission line and securely bond the filter to the transmitter cabinet using the provided mounting holes. Use a short coaxial cable with PL-259 connectors to connect the transmitter output to the filter input, keeping the unfiltered lead as short as possible. The antenna coax should connect to the filter’s output. Note that the filter may not resolve interference issues caused by poor TV receiver selectivity, which might require a high pass filter at the receiver end.

Installation / Setup
Before installing the TV-3300-LP low pass filter, ensure that your transmission line has a low SWR. This requirement also applies to the link between the antenna coupler and transmitter when the filter is installed in this location. It is important not to disconnect the antenna transmission line from the filter or disturb the load while the transmitter is operating, as this may cause the filter to break down. The filter should be installed on the transmitter cabinet and bonded to it using the provided mounting holes. A short coax cable with PL-259 connectors should be made to connect the transmitter output to the filter input, and this unfiltered lead should be kept as short as possible outside the cabinet. The antenna coax with a PL-259 connector should be connected to the output of the filter.
