Trunk Mount?

[jerneedog]

Would a Trunk Mount work on the hood of a truck like in this pic of
I_10_92's Truck, that was posted awhile back?

I'm wanting to do a similar setup with an Antenex ABSCANC antenna for use
with my hand held scanner.

If you do a little metal work to it. Trunk mounts are designed to mount on flat trunk lids - that hood looks pretty round. You'd need a trunk mount with enough metal that you could bend it into the inside curve of the hood. Other than that, and the need to feed the coax through the firewall, you shouldn't have any problem.

The bracket looks like an Antenex SBTB3400 with an Antenex MB8. The SBSTB3400 is basically a straight bracket with a 3/4" hole for the MB8 NMO mount. There is also an LBTB3400 which is an L bracket. Both of these are also available in chrome.

You can find the brackets at http://shop.waltel.com/catalog/index.php/cPath/1_72 , and the MB8 NMO mount at http://shop.waltel.com/catalog/product_info.php/products_id/178

Please let me know if you have any questions.

Thanks,
Jeff

Hi guys,

A HOOD mount? Ask yourself if you want to put up with all that engine noise, then reconsider. Unless you bond the hood to the body with heavy flexible straps it makes a very good antenna in itself and bonding is no guarantee it still won't act as an antenna on some frequencies. (resonance)

BTW, trunk lids also should be bonded but at the opposite end of the vehicle it's done for RF considerations when antennas are mounted there, not noise. In any case the hood should be bonded to reduce noise re-radiation.

The mounts that Jeff is talking about do not mount to the trunk lid or the hood, they mount to the body of the car under the trunk/hood lid, so there is no need to run a grounding strap from the trunk/hood lid to the body.

I've used these mounts too many times to mention on both hood and trunk applications with no noise problems at all.

I think what kb2vxa is referring to is the type that uses set screws to mount to the lid itself. Kind of like the old K-40 CB antennas. I have never used these. To me it looks like they put a crazy bend in the coax and that can't be good.

K-40 trunk lid mount

I just bought a brand-new K-40 CB antenna, and it came with that very lid mount with the severe 90 + degree bend.
Seems to work well, though.
A lot better than the Rat Shack magnet mount I was using, anyway.

Sounds like I might want to look into those grounding straps ... the hood hinges mount to the body, though, don't they?

I've got the "L" bracket (with a Larsen 150/450 dualband antenna) mounted on the LF fender of my '98 Chev. pickup near the windshield. I use it for a variety of radios, from an inexpensive RS SAME Alert wx radio to various handheld and mobile ham and commercial radios. I have NO problem with engine noise, nada, zip.
