My DAB preamp, the TGN Technology ULNA 3018 MK V, called it quits after less than two years—leaving my stacked DAB antennas hanging in the signal dust.
After a long wait I finally got a shiny new ULNA 3018 MK V—slightly upgraded—and braved the weather to swap out the old for the new.
Check out the specs below—gain, NF, and OIP—and see how it stacks up!
The ULNA 3018 MK V is coax fed by a 5 V DC power inserter.
The TGN Technology provided power supply feeding the inserter fits rather wobbly into this power inserter.
So I looked around for a better one and found Zolt 45 W universal net adapter from Amazon.
No longer a dodgy connection.
Just to be sure, I tested the old preamp on ground level with a simple DAB dipole… and surprise, surprise— it didn’t work at all. Looks like it was time for a upgrade—happy signals ahead!
