Low pass filter for 6m, 10m, 15m, 20m, 40m and 80m.
(all six filters are included for self-winding)
The kit is based on a solid board (65 x 110 mm) with low-pass filters for 50 Mhz, 28 MHz, 21 MHz, 14 MHz, 7 MHz, 3.7 Mhz. The filters can be selected with a rotary switch.
Using the SMA sockets you can connect it directly to your antenna, the QRP transceiver or the WSPRlite family.
The filter sets are also optional on request - please state as a comment on the order:
Deliverable sets: 160m, 80m, 60m, 40m, 30m, 20m, 17m, 15m, 12m, 10m, 6m, 4m, 2m
The board is already pre-equipped with the SMD capacitors, so that the
construction also aimed at beginners, whereby consistently high-quality components are used..
