Product Description
Attenuator VHF/UHF 20dB Variable/DC Blocked
A convenient variable attenuator which can be used with confidence wherever line-power is present. This compact unit is ideal for use on the inputs of distribution amplifiers and similar situations where signal level reduction and adjustment is required.
Features:
- Covers the return path, VHF and UHF bands (5-862MHz).
- DC-blocked at both ports - avoids burn-out when line-powered.
- Low residual insertion loss.
- Excellent flatness of frequency response across the full 20dB attenuation range.
- Surface mountable and includes a removable plastic body that allows easy connector/adjuster access.
- Tamper-resistant (access to the adjustment slot is recessed).
Technical Information:
| Product Code | Frequency Range | Insertion loss | Adjustment range | Flatness | Connectors |
| PROATT20V | 5 - 862MHz | <0.7dB | >20dB | <1dB | Type 'F |
DC-blocking voltage rating: 24V max. (DC or 50Hz AC).
This attenuator is not power-passing and is not recommended for use in the satellite IF band.
