it has a truly amazing ammount of total antenna miles and the power

even more amazing


forgot what it's called but if someone knows and u google it,
really
cool story and pix abound

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.

As a single antenna, probably.



Arecibo remains the largest fixed antenna.
The largest steerable is DSN... 70 m
ham : probably the low band beam used by JARL ?

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!

Sounds like they collected the whole set!

Beware of the Antennaphobes

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.

The Sun for transmission, and the earth for reception :)

Bigger maybe? -- http://www.aoc.nrao.edu/

If you exclude various multi dish arrays then the biggest is Arecibo radio
telescope in Puerto Rico.


I think you will find some vlf arrays which dwarf it.
