Hello
I am going to be aiming a C-band sat. antenna ("dish") that operates
around 4GHz. The PLL/LNB on the receiver will divide this frequency to a
more usable L-band of around 750-850 MHz. The PLL/LNB is powered by
24VDC on the signal cable. There is a splitter that injects this voltage
into the signal cable [75 ohm RG11].

To get to my question: I will have to hook up a 2GHz spectrum analyzer
to help aim the dish. I would like to block the DC. Can I build an
adapter with a small value capacitor and expect it to work? Keeping
leads short and everything shielded as best I can, etc.

Thanks
