3(.0)-30MHz SDR Full HF Band Pass Filter, Receive Only, Bi-Directional, 50ohm

Description

I live in a mid-sized metro area with saturated airwaves. I've tried AM and FM band stops, and all the filters in my SDR, which was still overwhelmed. I started looking for a receive-only 3.0-30Mhz BPF and could find nothing that wasn't a brick made for transmitting 100W. So I worked directly with a manufacturer to place a small order. I figure there might be a few HF enthusiasts who'd find this filter useful.
In my set up, the RF power out of the filter is <10% than in. So I have inserted a 10db LNA and get great results. My current record is BBC Madagascar (>8,000 miles).
Maximum input power 100mW (maximum input signal strength 20dBm). Bidirectional. Weighs approximately 31g. Length with SMAs, approximately 61mm.
PLEASE NOTE: This is a
receive-only RF filter. It cannot tolerate DC current without damage.
The filter is a combination of a high-pass and a low-pass filter.
Do not attempt to transmit through this filter.
The filters are tuned individually, thoroughly tested, and run for 2 - 4 hours in the factory. I test each with a spectrum analyzer and record the results.
Returns in like-new condition, and that test functional, will be refunded at buyer request. Please consider contacting me before requesting a return. We can work with the factory to determine if your unit is defective or has been damaged.
