Do the DX Engineering RG-5000 device, or the AS-RXFEP from Array 
Solutions) behave nicely when hit with a signal well above their 
protection threshold, or dothey generate interference (noise, harmonics, 
intermod) from the energy that is blocked?

Our particular application is for the RBN, involving a QS1R receiver 
very close to the antennas of an HF ionospheric radar operating on a 
couple of discrete frequency bands in the 8-18 MHz range with about 1 KW 
input (don't know what the EIRP would be at the location of the receiver).

Dx Engineering says their version offers "far lower harmonic and noise 
products across the spectrum than any competing RX front-end saving 
device,"  Would sure like to hear some impartial confirmation.
