Fea tures

The APD4+ is equipped with TNC type con nec -
tors. Low loss co ax ial ca bles are also sup plied
for split ter to re ceiver an tenna jack con nec tions.
The APD4+ has an in ter nal power sup ply. Power 
out jacks and ca bles are pro vided to sup ply up
to four re ceiv ers thus elim i nat ing ex cess power
