I think he's referring to the 300-75 (4:1) ohm baluns that match 300 ohm
twinlead to 75 ohm coax. They typically have two screw terminals
for the VHF twin lead, (and sometimes two additional screw terminals
for the UHF loop), and one type F 75 ohm connector.

Are these VHF TV baluns an inexpensive choice for, say, a homebrew 2 M
(144-148 MHz) beam to be used at QRP levels (or in my case, solar radio
astronomy)?

And the orginal question I believe Peter posed was, are these baluns useful
for HF (1-30 MHz) at QRP levels?
