Not good enough. If you just crammed a 68 ohm resistor into the
F-connector jack, you probably have a fairly good approximation of an
antenna. It's going to radiate junk, and pickup more junk (ingres).
If you insist on doing it like that, wrap the resistor with some
insulating tape, and then cover it with aluminum foil.


Do you have any idea what the wavelength is at 600MHz? It's half a meter
(Meters times megaHertz equals 300). That makes the length of a quarter
wave is 1/8 meter or about 5". A tiny resistor is not going to radiate
efficiently enough. If the "splitter" is a hybrid the unterminated port
will cause higher attenuation through the splitter. Maybe a single dB.
Not important when receiving.

You'd be better off getting a DC block. The splitter loses at least 3 dB.


A DC Block is nothing more than a capacitor between two connectors.
Some use more than one capacitor to extend the usable frequencies. I've
used up to five to have a flat response from 100 KHz to 1400 MHz at 50
Ohms for a production test line. The insertion loss was about .1 dB at
each end of the usable range.
