Has anyone measured or tried the tv cable splitters on the low frequencies
(1.8 thru 10 Mhz)? I wonder if they will work to combine 2 RG-6 phasing
lines from pennant or flag antennas to a feed line to the shack. The one I
looked at said for 5 to1000 Mhz but I'm not sure if that rules out 1.8 Mhz
or not.
Also I'm thinking of building the K3LPL receiving filters described in an
e-mail on this site several months ago. What I'd like to do is build the 80
and 160 filters, but build them with a 75 ohm input on one end and 50 ohm
output on the other. Frank says that the C1 and C7 capacitors are sized to
act as voltage dividers to match the resonators to 50 ohms. I'd like to
change either C1 or C7 to match 75 ohms so I can use RG-6 from the antenna
and RG 58 to the radio. Can anyone tell me what size to make either C1 or
C7 on the 80 and 160 meter filters to match 75 ohms. I'd like to understand
the theory and formulas to make this calculation if you can tell me wher to
find the info. Please respond to NW6S@arrl.net so we don't clutter up a lot
of peoples mail boxea with my simplistic questions. Thanks in advance for
taking time to answer.
