So what did they do with those antennas in your area? I find lots of references but can't even find and old history picture

Keep chattering away, you still can't do anything about it.

4 Outline of possible new (non-traditional) uses of the new radar
The objective of this item is to evaluate the feasibility of different “unusual” applications of the new radar based on the results of the literature search. The applications and brief preliminary conclusions are as follows:
• Artificial ionospheric targets. Possibly new applications of ionospheric releases of small particles fabricated using modern nanotechnology methods that may induce very large radar cross-sections to ISR in the ionospheric environment.
Experiments involving artificial ionospheric injections of different materials were conducted in the 1980’s. For example, Millstone Hill 440-MHz ISR was used to observe the spatial and temporal development of heavy negative ion plasma clouds created during four active chemical release experiments: the Ionospheric Modification Study (IMS) in 1983, the Space-Plasma Negative Ion Experiments (SPINEX 1 and 2) in 1984 and 1986, and NICARE 1 in 1989 (Sultan et al., 1992). The METAL campaign (Kirkwood and Vonzahn, 1993) was a multi-instrument campaign conducted in 1991 that was designed to investigate the relationship between neutral and ionized metallic layers in the high-latitude lower ionosphere. Measurements included electron density profiles and electric fields from the EISCAT UHF radar, ionosonde measurements of E(s) layers, neutral Fe profiles from lidar, rocket observations of winds (by chaff releases), and measurements of plasma density and ion composition (by mass spectrometer). The Arecibo incoherent scatter radar was used to observe enhanced ion acoustic and Langmuir wave turbulence after the release of 30 kg of CF3Br into the F region at 285 km (Bernhardt et al., 1995). In July 1992, as part of the NASA Combined Release and Radiation Effects Satellite (CRRES) El Coqui rocket campaign, the AA 2 experiment was performed. Its purpose was to study the interaction between a powerful radio wave and a high ion mass (Ba+) ''collisionless'' plasma. Approximately 35 kg of Ba were explosively released near the center of the Arecibo high-frequency heater beam at 253 km altitude (Djuth et al., 1995). Barium cloud releases were studied by Sridharan et al., 1997. Among other materials used for active experiments the following can be mentioned: metallic needles (Goldstein et al., 1998), CO2 (released near Millstone Hill ISR, Semeter et al., 1996), trimethyl aluminum (Roper, 1996).
