Preamp

[jazzboypro]

Hello all,

I was talking with a friend last week and he talked about a company called Advance Receiver Research. He was talking about their preamp for amateur use. Here is a link to their amateur preamp line

Do any of you have experience with them ? Are they any good ?

Many thanks.

Sorry i posted the wrong link. The link for the amateur preamp line is this

Good coax has little loss at the lower frequencies, maybe for a long run like 100 feet or so on UHF the pre Amp would be worthwhile. For the Ghz stuff , now that's another animal.

I should have mentioned that this question was related to another post a made a few minutes before about a satellite antenna. I suppose that the signal received by the satellites/ISS is not that strong.

Are they any good ?

If you look at their best $120 VHF amp it has 0,5dB NF and its 1dB compression at 12dBm.
Compare that to a $15 PGA103+ amplifier that has the same NF but 1dB compression at 22dBm, a 10dB improvement.
Data sheet here

They don't mention IP3 intermodulation level, as its probably not very impressive, that are 40dBm for a PGA103+ that would be hard to beat.

ARR preamps have really good specs if you go back to the 1970s. By todays specs they are junk for the $$. The MiniCircuits ZX60-P103LN has low noise figure and good IP1/IP3 specs but a lot of gain at VHF or UHF. If you use a band pass filter in front of it and attenuate the output it should be very useful and I’ve used them on VHF and UHF repeater front ends with great results.

Thanks for all the info, i will look at the other suggestions. Not sure at this point if i will need one.
