DX Engineering Type F Coaxial DC Blocks
DX Engineering Type F Coaxial DC Blocks have a male F connection for the equipment and a female F connection for the antenna line. When inserted into the line in either direction, they block DC current from passing through while permitting RF signals to flow. These units effectively block DC current from entering where it's not wanted—on antenna lines where DC powers other devices. The blocks will keep DC out of your receiver input! Their straight, inline form factor is perfect for most applications. Use these DC blocks at frequencies from 5 to 2,500 MHz! For example, they're ideal for isolating amplified Sirius/XM antenna voltage from your receiver. They easily handle up to 24 Vdc. Block that DC!

DX Engineering NPA RF Attenuators
DX Engineering NPA RF Attenuators reduce the amount of signal carried within coaxial cables. This signal attenuation is sometimes needed to ensure proper receiver operation. When amplified antennas and inline amplifiers are used with short cable runs, it's possible to have too much signal arriving at the radio. Excessive signal may over-drive the receiver and create distortion or self-generated interference. When this happens, knocking the signal down a bit is the best remedy. DX Engineering RF Attenuators are Non-Passing Attenuators (DC blocking) in 10 or 20 dB attenuation levels. They may be combined for attenuation levels beyond 20 dB; however, this is very rarely needed. Operation is from 500 kHz to 2.4 GHz. When you suspect that you have too much signal reaching your radio, grab one of these DX Engineering NPA RF Attenuators!
