    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

This seems like a good antenna for Us Railfans

This is commonly referred to as a Firecracker antenna. You need a really good ground plane for this thing to work right. I had a friend who had one of these off of an old locomotive, and he had a lot of problems with it. he had it mounted on the roof of his car.

Hey all. I was noticing that locomotives have a strong signal. I think I might get this ;)

That's a Firecracker antenna. Needs a really good ground plane to work effectively and is usually seen mounted on top of the locomotive cab.

Many railroads (at least in the eastern US) have gotten away from using this antenna as they're too subject to damage from low-hanging tree branches. A 1/4-wave whip is just about as effective and just snaps around when hit by a tree branch (usually). Plus, it's essentially a unity-gain antenna, and isn't much better than a 1/4-wave whip.

If you're looking for something for the house, go with something designed for base use in the VHF band. For mobile use, get a mag-mount 5/8-wave VHF antenna (unless you're willing to punch holes in the car for an NMO mount in which case you can get a 5/8-wave NMO-mount antenna).
