I've been thinking about something. Yeah o think about a bunch of stuff all the ti e. What are the possibility that you could add a chain or a real antistatic ground strap to your car. Would adding that and making a better ground from the car to the real earth make the ground plane work better? Yeah itll help with static build up but what would or could it do to the efficiency of a mobile antenna?

Anti static strap on a car and antenna proformance

I did it once, noticed no difference.
It probably depends on the source of static to whether it'll be effective.
Many fuel tanker trucks have used them attached to the trailers rear axle dragging on the pavement as a way to help static discharge but I don't notice them anymore.
These trucks today use a scully ground hookup when loading fuel to be used for grounding and static discharge.

Yea. Open car doors. You will extend counterpoise.
A friend of mine, while dxing from static mobile is adding 4 quaterwave horizontal counterpoises made from copper wire to antenna mounting point. It improves antenna performance.

Those static straps are just meant to prevent static buildup to stop getting a static-shock when you get out of the vehicle. As for enhancing your RF ground...........nope. The wire is not always in contact with the ground while in motion. It bounces around. Also, it is of far too small size to properly bond to true earth ground. Thirdly the vehicle has a fairly decent coupling to true earth ground via capacitance. That's a lot of surface area.
if you want to dissipate static from a mobile antenna, you need to DC ground that antenna, and the way to do that is with a small inductor connected at the feedpoint going from center conductor to shield.
the value and characteristics of this coil must make it look like a high resistance at 27mhz, but it will act like a short for DC.
no, i do not happen to have the dimensions of such a coil handy.

i run static straps on my blazer, no difference in rf side,, but stopped getting a static shock getting in and out of it,,,,
That is their ONLY purpose,,,, to prevent getting shocks while getting in and out of the vehicle. There is NO WAY they can enhance an RF ground.
- No one is chatting at the moment.

@ BJ radionut:Ham radio operators (VHF/UHF) should pay attention to enhanced radio propagation paths throughout the middle latitudes and equatorial region, a common occurrence following such events.

@ BJ radionut:Had "Aurora" propagation on CW/SSB on 6m last evening. (300-700m range here) The 2m guys had lots of Ducting/TROPO between the East Coast and Gulf Coast op's, even early today.
