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 ?

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 don't see insertion loss mentioned in the specs for the Mini-Circuit LNA.
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.
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.
What is the cost of the ZRL-1200+?
Something wrong with your fingers? ;o)
$120
And most people would link a source to an response, but I guess that would have been asking too much.
I would think any loss within the preamp would result in some loss of signal to amplify to begin with before the receiver.
The Stridesberg preamp shows loss because it has bypass relays and the loss is when the preamp is bypassed. Otherwise a preamp has no loss spec.
Yes, I have one. That's why I use other much better amplifiers and splitters. Why can't Stridsberg use top of the line components in their expensive devices?Ubbe have you ever tested a STRIDSBERG?
