The manual provides instructions for installing, operating, and troubleshooting the TV-100-LP and TV-1000-LP low pass filters, emphasizing the importance of maintaining a low SWR in the transmission line and proper installation to prevent filter breakdown. It also discusses the effects of filter insertion on VSWR and provides guidance on achieving optimal filter performance, while noting that the filters are not a solution for TV receiver design limitations regarding selectivity.
Manual Overview
The manual for the Drake TV-100-LP and TV-1000-LP Low Pass Filters provides detailed installation instructions, emphasizing the importance of maintaining a low SWR in the transmission line. The filters should be installed on the transmitter cabinet, and the unfiltered lead should be kept short. The TV-100-LP filter requires soldering into RF-58/U coax, with optional SO-239 connectors available for purchase. Installation involves stripping the coax, soldering the braid, and securing the filter with screws. The manual specifies power ratings for each filter and provides guidance on matching the filter to a 300-ohm balanced line for 6-meter band operation. The filters are tested with a 52-ohm resistance load, and adjustments are made to ensure proper cutoff and attenuation. The manual notes that a moderate increase in VSWR upon filter insertion does not significantly affect performance. It also highlights that the filters may not resolve interference issues with TV receivers, suggesting the use of a high pass filter instead.
Quick Issues Covered
- Diagnose VSWR changes after filter insertion in transmission line.
- Adjust coil and condenser for proper cutoff and attenuation.
- Trace circuit using schematics for coaxial connections and ground lugs.

Installation / Setup
Before installing the TV-100-LP or TV-1000-LP low pass filters, ensure the transmission line has a low SWR. The filter should be installed on the transmitter cabinet and bonded using the provided mounting holes, keeping the unfiltered lead as short as possible. The TV-100-LP is supplied without coax connectors, allowing for a cost-saving installation by soldering it into RF-58/U coax. If desired, SO-239 connectors can be purchased and installed. For installation without connectors, the coax must be cut, stripped, and soldered according to detailed instructions. Care must be taken not to deform coils or melt inner coax insulation during installation. The filter’s bottom cover screws can be used for mounting on the transmitter. The filters are checked with a 52-ohm resistance load and a wide band sweep generator to ensure proper cutoff shape and frequency. A moderate increase in VSWR when the filter is inserted will not significantly affect the filter’s performance. If the filter is used in the receiver circuit, adjustments may be needed to restore impedance match.

Safety & Warnings
Do not disconnect the antenna transmission line from the filter or otherwise disturb the load with your transmitter operating. Removing the load from the filter may cause it to break down. Be careful not to melt the inner coax insulation when soldering. Be careful not to deform coils on the filter board during installation.
