As has been discussed before, a splitter intended for home satellite
systems is a cheap solution as they have the bandwidth and the DC pass
required. I have one between a couple of Thunderbolts. It powers the
antenna and shows antenna OK on both. Using a splitter is better than
just a T as it does lend some isolation between the receivers.

I think I should have said that my box is only 25mm high. So any splitter
will have to be less. A Mini Circuits splitter will just about do it , but I
would prefer a smaller solution.

Hi,
Till now I have been putting receivers in individual boxes. So to limit the growing number of boxes, I want
to put two Resolution-T SMT receivers in one box, sharing power and antenna inputs. My question is " How
best can I share the antenna input, minimizing any interference between the receivers?" . Will any
interference matter? For example, I can easily connect three bits of shielded coax in a "Y" , but
will probably get reflections from each receiver. As the cables will only be about 15cm long, would it
matter? How about the DC antenna supply? The antenna DC will NOT be powering an antenna as it passes through
a DC blocked splitter used to share an antenna between most of my receivers. I might be able squeeze a
Mini-Circuits splitter in the box and DC-block both outputs but that may be overkill. What discrete
circuitry might be a replacement? Will the "Y" do it?
Someone must have already succeeded with this type of config.
Thanks in advance for your input.
Regards,
Mike
