These might have been made in 70's or 80's not sure. Professional I think.
Can anyone tell me how much one is worth? I mean, what would be a reasonable sale price for one of these oldish Anritsu inline attenuators? It good from DC to 5Ghz. Might put them on Ebay but I need some hint as to a buy-now price that's an absolute bargain, but is not exactly a total giveaway. Thanks.
