Re: [time-nuts] HP-58532A antenna

I actually bought one of each of the antennas, just haven't gotten to mount them outside yet. I plan to do some simple tests against each other but do not have the expertise or equipment to run any in-depth measurement. --- Jose V. Gavila [EMAIL PROTECTED] wrote: Hi Colin, I just

Colin, The HP58532A is also commonly known as the VIC-100: http://pewa.panasonic.com/emp/products/gps_pdf/Panasonic_VIC100_Antenna_9_06 .pdf. Lucent had a special modified version produced with a lower gain LNA for short cable lengths. The KS spec you supplied is Lucent's P/N for the low gain
