Early meteor back/forward scatter work was started in lower VHF
frequencies. At one time it was discussed that frequencies of 10/11
metre were in the VHF range --very high frequency. Interesting
electromagnetic frequencies in the 29-30 to 50 mHz range can be
reflected. Early radar work was in this range.

Again please see the AMS site:
The American Meteor Society, Ltd. (AMS) Radiometeor Project
http://www.amsmeteors.org/radio/poplar.html

or for a history of listening to meteors in 1940-1950 see

http://leonid.arc.nasa.gov/GlobalMSNet/QST-July-1947.htm

Also if you have access to a library -- see magazines from 1950 to 1960
--"Radio and Television" "Popular Electronics" articles about TV DX --
Television Distance. DX is radio slang for distance. Before the
explosion in wireless devises -- it was possible on a good day to site
in Exeter and "see" a  television test pattern from Oslo. The frequency
was between channels 2 (54 mHz) and 3 of a television. Direct antenna.
No cable no dish.
