![]() "Scott" wrote in message ... The ELF antennas in Michigan and Wisconsin were bigger than 70M. Each was 13 miles long. Wisconsin had 2 antennas and the Michigan site had 3 antennas. The patterns were steerable electronically by changing the current phases. Simple stuff. I used to work there. For sure that any ELF system, due to the wavelengths used will be always very loo-ong and the longest system. In this context we can also speak about HFGW and space VLBI. But speaking in term of HF and microwaves, Arecibo and DSN remains the largest. All depend on what frequency bands are concerned.

Arecibo remains the largest fixed antenna. The largest steerable is DSN... 70 m ham : probably the low band beam used by JARL ? 73 Thierry http://www.astrosurf.org/lombry But as an 'effective' antenna what about that line of dishes on tracks near Cambridge that ISTR is equivalent to a dish 3 miles across! -- Woody harrogate2 at ntlworld dot com |

Project Sanguine was the prototype built in the 50s or 60s in Clam Lake,
WI. Mothballed after the test transmitter was built. When the project was rekindled in the 1980s, it was simply called Project ELF.
