In order to test the filter I got via ebay, I just connected it outdoors, not really the best thing to do.
Today I went to the local "elektronica-boer" and got some connector adapters making it possible to move the filter indoors. I had to retain the filter before the extra indoor amplifier in order to avoid IMD problems, so a bit of extra adapters were necessary.
