? Advanced Receiver Research (AR2) Receive Only Broadband Pre-Amplifiers ?
I've heard nothing but good things about ARR gear. However, you are
probably correct that most situations will not find this preamp to be useful. How about following this preamp with a passive splitter to make a low noise multicoupler?

Or - OutSide the House at/near the Antenna to Coax Cable Feed-in-Line junction. i want to know ~ RHF . . How would such a device help anywhere but on a DXpedition where the background noise is very low? |
