So I've got a big antenna for my Yaesu 2900 that I put on the hood. It's fine but it sticks out on a bit of an angle.

I'm wondering if it'd be better to place on my front Shrock or my rear Shrock bumper? I'm not going to put it through the roof.

Also, can anyone recommend a good short / stubby antenna I could use instead?

I mounted my CB Antenna on my front shrock (I know it's a different frequency range, but RF theory still applies) and it works very well. It helped with the CB antenna to get it away from the body of the vehicle. The shrock works very well as a grounding point all though probably doesn't create nearly as good a ground plane as the hood does. I am planning on installing a VHF whip up there as well though.

Honestly, I know you said you don't want to use the roof, but I use a mag mount, dualband antenna (VHF/UHF) up there sometimes that works really well. Probably just the over all better line of sight, but worth considering.
Personally, I'd avoid the rear bumper, I just feel like the body of the vehicle really tends to get in the way at times. At least the front offers relatively low interference.


When you say short/stubby antenna, how short are you talking here? What wavelength is the one you are using now?

What's the mount you're using for the antenna? Something like the Diamond K400 gives two axes of adjustment, and should be able to get your existing antenna vertical on the hood lip ... provided that you can find one with your antenna's specific interface - which you should be able to, they make the K400 with pretty much every available interface out there. HRO (www.hamradio.com - search "K400") has pretty much all of them, and some of the best prices around ... not to mention good stock and great service.

I noticed with the K40 lip mounted whip that I use for my CB, that only has one axis of adjustment, that there's still a pretty good forward rake to the whip ... which was kind of a bummer. Putting a whip on the edge of the hood is a great antenna placement, but it really illustrates how much adjustment is necessary if you're at all anal. I am, and the forward rake bugs me ... to the point that I've actually considered going to a new CB antenna setup that would eliminate it. :geek:

Thanks for the input guys - I'd basically like a smaller antenna (18" maybe?) that I can use around town, and keep the larger one for when I really need communication.

The thing is I've had my HAM license for about a year now and find I barely use it. I'm about to head out on another long roadtrip across the continent and I'm thinking I'd like to have a smaller antenna I can leave mounted that's good enough that I can pick up NOAA and anyone relatively close to me.

I don't want to break the bank either by buying a new $80 mount.

This is my current antenna:

You can see how it sticks out:

I use this Comet lip mount in about the same location as your antenna:

This mount allows me adjust the antenna so it doesn't stick out to the side. In fact, I have the antenna slightly tilted toward the middle of the truck to help avoid branches.

And this is the Diamond antenna I use (it is longer than 18", but still short enough to not hit the garage when I enter):

I have my Yaesu FT-8800R under the driver seat, and the face plate mounted in they console tray.

My antenna location almost certainly affects the antenna radiation pattern, but it works well for me.
