I was wondering if anyone has tested one of these or has thoughts on this New preamplifier ? It's pricey but was wondering how well it performs ?
I don't see insertion loss mentioned in the specs for the Mini-Circuit LNA.Its pricy because it has bypass relays inside so when you remove power it switches the preamp out of circuit and lets the unamplified signals pass through. Otherwise the specs are not that impressive. If you just need a preamp and no filtering or relays this one is only $40 and the specs are much better. I just put one in the front end of a 900MHz repeater and its working very well. Mini-Circuits
I would think any loss within the preamp would result in some loss of signal to amplify to begin with before the receiver.I'm not the sharpest tool in the shed, but I'd "think" any insertion loss in an amplified circuit would be negated by the amplifier gain...but I could be wrong.
What is the cost of the ZRL-1200+?If you want the wider frequency range then you'd probably need something like this: https://www.minicircuits.com/pdfs/ZRL-1200+.pdf
I don't see anything from MC that works between 700-900 Mhz...
And I'd highly recommend a quality filter on the input (before the preamp) if you're going to use this on an external antenna.
