The BCC splitter design suggested by PC2A is based on the "magic tee" splitter.
An excellent tutorial on magic tee splitters can be found on W8JI's Web site:
https://www.w8ji.com/combiner_and_splitters.htm. These splitters are very
easy and inexpensive to build.
A 1:2 splitter design using a single ferrite core can be found here:
http://michaelgellis.tripod.com/magict.html. See Figure 7. There is -3 dB
throughput from the source to each load port. This splitter introduces a 180
degree phase shift between the two output ports but this is irrelevant for
splitting a receive antenna between two receivers. I have built many of these
using Fair-Rite 2873000202 cores. For a 50 ohm system, change the 37.5 ohm
resistance to 25 ohms. Use 7 turns (28 AWG magnet wire is suggested) through
the binocular core on the source side and 10 turns center-tapped on the load
side. This will provide a 50-ohm input impedance on all ports and excellent
isolation (>25 dB) between the two load ports.

Hi
May I throw up the BCC splitter?
