); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY 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 to construct.
Email me off list for scanned copies (PDF) - approx 7.5M file.

It is outside on a tripod, about 12' to the base. Very broadband and omnidirectional. 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 (bi)directional. 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.
