Shorter antenna

2014 F 150 and I would like to get a shorter antenna to avoid the slapping on the garage door.  I did the Googs and saw all sorts of them for under $20.  I don't know anything about this stuff and wonder if the baby ones work.  Any recommendations will be appreciated.

Thanks for your time.

Tom

Ordered a replacement on-line.  Seems like it's a common thing.  The cutting off and a wire nut may have worked and maybe I should have tried it.  Live and learn.  At least if the stubby doesn't work I can go back to the big one.

Good luck with reception with a stubby. An FM antenna needs to be a 1/4 wavelength tall; ie; approx 75 cm or about 24.5".   As you drop past that, reception plummets. Motorheads know that one by heart. That's why I cut off 3" and went with that.

Motor heads know about antennas and electromagnetic fields? 

 

Guess they missed the part about how adding inductance can tune an antenna that is shorter than quarter wave.

What are ya, a parrot? Someone needs to tune you...with 220 volts of inductance. *ZZZZZT*

Well you guys could have given me this info before.

The replacements most likely have tuning components built in.  And it isn't too big a deal anyway if you have decent signal strength.

Ya, right. HAHAHAHAHAHAHAAHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

 

From a car audio site....MOTORHEADS talkin'...

 

FlyinMiata9,
A shorter antenna mast captures a smaller portion of a radio broadcast station's travelling radio wave. That results in reduced radio reception capability. The reduced radio reception capability may never be noticed if only listening to nearby radio broadcast stations in the city. 

There's no overall magic of one short antenna over another. There are some that include a signal amplifier. They can at times enhance more distant radio receptions, but usually degrade other radio reception situations, often those where there are multiple strong radio signals in the reception area.

The overall disadvantages of antenna amplifiers for car antennas tend to be far more predominant than advantages. There are some radio signal amplifiers for car antennas that automatically switch "off" when operated in a strong signal area. That can assist clearly listening to the nearby strong radio stations, but reduce the prospect of listening to any some distance away.

There's always a prospect of the antenna you installed being defective, or not installed properly well mounted to the car's fender for a good electrical radio reception ground plane. Check to make sure the in-line Motorola connector set is fully pushed-in inserted together. 

A simple way to test the antenna line and system is to tune in a weak AM radio station in the daytime and then grab hold of the antenna mast to detect stronger and louder reception of that weak AM radio station. Your conductive body mass adds some to the short antenna's reception capability. There may also be an initial "thump" sound as the car's radio makes an automatic adjustment of its radio reception sensitivity. If there's no dramatic change in weak AM radio reception, look for an open or shorted electrical problem. Best bet is a full length proper antenna.

I'm not fighting with anyone.   Many ways to make antennas, and for receivers in cars wavelengths aren't all that important.   Class up your vehicle with a wire nut or a fox tail or whatever you like.

      As a recovering machinist, I can appreciate that.  If the spec is 0.001 - 0.0015, then clearly the correct measurement is 0.00125, duh…

      I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought. Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...

      Congrats on the motor!  I think you’ll like it.   I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers.  160 degrees is more than I expected to hear.   Curious why you’re opting for a 3 bank charger with a 24V trolling motor.  Unless you don’t feel you be running you big motor enough to keep that battery up as well?

      I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius) says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.

      Wasn't terrible at a state park beach. Antelope island maybe.  I wouldn't recommend it as a beach destination tho.  Figured I was there, I'm getting in it.

      The water looked and smelled disgusting with hundreds of thousands of birds sh*tting in there.  About as gross as the Salton Sea. When I duck hunted there I didn't even want to touch the water.

      It's kinda gross with the algae in the summer but I got in it anyway.  Wanted to see the increased bouyancy at work.  You can kinda tuck yourself into a ball and you'll just float with your head above water.  When dry off you look diamond encrusted with the salt.

      We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.
