Manufacturer's Description

• This electronic gadget allows the original fitment Japanese radios to receive all English frequencies. 

• Simply connect in-line in the aerial lead, and connect a single wire to a positive feed. (No need of confusing instructions)

• Receives all stations from 88Mhz to 108Mhz. Full frequency range 88-108Mhz with one Band Expander 

• It achieves this by shifting the UK transmission frequencies into the band that the Japanese radio will detect.

• RELIABLE each unit is individually precisely tuned for desired band on appropriate RF test equipment. 

• Built in amplifier to improve reception. 
  Built in Blocking Filter (extremely important to eliminate original frequencies radio is tuned to from 76-88Mhz to avoid any possible 
    radio interference). 
  Input and Output are preciously matched to improve sensitivity. 
  AM bypassed (without change )

If you fit an expander this means the radio signal you receive is 20Mhz higher than the radio display. Therefore when the radio shows a display of 80Mhz you will be receiving 100Mhz. With an expander fitted you can receive most of the UK stations
