Since I already have the passive Stridesberg, and the GRE is only $40,
I'll go for the GRE and add a tee network pad to tame it to the min gain I want, e.g. if the GRE min gain is 10 db as stated herein and I need 4db to make up for the coupler losses, then I'll add a 6-7 db pad to the output of the GRE to do the job. I suspect the BC-780xlt may howl on certain freqs but the R-7000 will be OK. That thing is bullet proof. 73 Tom GeorgeF wrote in message news:3F8B5B34.9030700@licensed4funREMOVEBEFOREFLI GHT.com...

When you add an attenuator, GRE pre-amp, and non amplified Stridberg you might be just as costly as buying the amplified version and not have the extra hassles.... Also remember the GRE preamp probably has a higher noise figure than the amplified version of the Stridsberg. George http://www.MilAirComms.com |

I reviewed a GRE Super Amplifier in
April 2003 Monitoring Times. It is the smaller model, designed for use with portable scanners. The GRE Super Amplifier I tested (s/n 93156349) is best suited for improving the performance of insensitive scanners and test equipment when used with an inefficient antenna. You may experience intermod if there are strong signals in your area. -- ================================================== ======================= Bob Parnass, AJ9S GNU/Linux User http://parnass.com |
