[QUOTE="s-band, post: 972635, member: 407744"] VS, how long is the RG58? The PSA4-5043+ has about 15dB gain at 1.5G and 1dB NF. If you've go a long bit of RG58 you may be losing a lot Your S/N on the 200kHz wide sig is at least 20dB less than I was getting using <1/2 of the 1.5m's area. You're looking for a gross problem not the last few dB. Are you seeing preamp noise when you enable it? You should be if it is overcoming the cable loss You're still in the footprint [/QUOTE]
