SCR-717C and RC-266

[MarkN]

Hi

Anyone have any details or references to the performance, improved or otherwise, of the SCR-717C with the RC-266 truncated Parabolic Antenna versus earlier versions with the RC-224/226 antennas.

Some equipment listings also show an RC-284 as an improved version of RC-224?

I am trying to compare the possible sea search performance of the SCR-717C and ASV Mk7A or H2S Mk3G.

thanks

Mark
