CD Series VHF/UHF Couplers

ERI CD Series VHF/UHF Adjustable Directional Couplers are
designed and manufactured to cover 50 MHz to 860 MHz with
a broad coupling range and corresponding directivity, all within
one of the smallest packages in the broadcast industry. The
coupling loop provides high accuracy in forward and/or reflected
power measurements necessary for determining VSWR, com-
ponent or system losses, line power, or other operations. Etched
angle and penetration scales provide ease and accuracy in
measuring coupling values across the FM/VHF/UHF frequency
bands. Nominal Directivity is at least 30 dB and typical values
of directivity can be significantly higher upon final adjustment.
These couplers can be implemented in any of the standard
coaxial line sizes. Single, dual, triple, and quad couplers are
also available.
Saddle type field install couplers are also available with the
same functionality and performance as the ERI CD Series VHF/
UHF Adjustable Directional Couplers.
