[time-nuts] LORAN-C antenna

I have read with some interest the thread on LORAN-C antennae. Although over
20 years since I was actively involved with Austron & LORAN-C, I have data
sheets and an installation instruction sheet on their 2026W Whip and 2021L
Loop antennae. All give dimensions which may be of use if anyone is planning

I am using a commercial active whip antenna, McKay-Dymek model DA100A.
It is outside on a tripod, about 12' to the base. Very broadband and
I use for VLF RX on 137 and 185 KHz as well as RX during HF FMTs.
A resonant magnetic loop antenna may have enough bandwidth, but will be
100 KHz Loran-C stations near you are:
Malone, FL, master on GRI 79800 and secondary (W) on GRI 89700
Jupiter, FL, secondary (Y) on GRI 79800
also secondary stations in Carolina Beach, NC and Grangeville, LA
if you need station exact lat and long, let me know.
