Low Pass Filter (About Time!!!)

Using a kit - and my own wire - I constructed a 20m low pass filter with the clear intention of putting my radio on the air. 

The insertion loss was not nearly as high as I had expected - a good thing in my case.   The insertion loss was about 0.70dB around 14.3MHz, while the attenuation at 28MHz was over 50dB.
