Firecracker Antennas (as freight)

Early 1950's is when they were introduced. This is a 1955 photo.

The upright antenna is almost invisible - just a "whip" antenna.

Sorry Jeff but antennas were sometimes transported in freight cars, so this is a cargo commodity we're talking about. :-D

They are still manufactured by Antenna Specialist model ASP-16. It's 11.4 inches tall. It currently sells for $293. 

Looking in the Diesel Spotters Guide the GP-18 in 1963 had one. 

U25B and U28C manufactured in the mid 1960s had them.

While setting up my new Athearn CB&Q GP-7 241, I noticed a firecracker antenna on the roof. Athearn’s CB&Q GP-7 218 doesn’t have one. What year were firecracker antennas introduced? My F units with antennas all have wagon wheels, so I’m trying to avoid anachronisms. I have photos of #241 with and without the firecracker antenna, but I don’t have any information about when it was installed. The side sill strips are red and yellow before Scotchlite safety stipes were used. One of my 241 photos also has a GP-30 I Chinese Red and Gray, if that helps date the firecracker.

Thanks, Tim. Sounds like I need to check the delivery dates for the late Q road numbers to see if they might have come with antennas, though of course the railroad could have installed them after purchase. There’s a great two part Burlington Bulletin on the SD 7s and 9s, but for some reason the GPs haven’t been exhaustively covered in bulletins, so most of the modeling information about the GPs has to come from photos.
