SECTION 4. CIRCUIT DESCRIPTION UHF BAND (380–479 MHz) 4-1 RECEIVE CIRCUITS The RF signal from the antenna is passed through the LPF RF CIRCUITS (MAIN UNIT) (L90, L94, L96, C409 and C418) and HPF (L84, L88, C391, VHF BAND (108–174 MHz) C395 and C402) and ANT SW (D68, D73, D75 and D84), and The RF signal from the antenna is passed through two LPFs then applied to the RF AMP (Q23).
