On a couple of occasions I have noticed vehicles with a tilting bracket on the bullbar for HF/long aerials allowing the aerial to be tilted backwards to allow access without the removal of said aerial to shed /carport etc.Does anyone know where one might obtain one?Many thanks,Mary

Mary,
Try any of the ship
chandler type
places, like Whitworths.
They stock marine bases that will tilt. Think some of the more resourceful members make their own, out of RHS, and a couple of bolts etc.
The GME/Electrophone website may have a base that would suit your needs too.
Hooroo,
Bob.

I had one made by a Member here by the name of JD, as I recall.
I could send a photo to you if you wish. Just contact me through my website below.
Cheers

Mary,
you can try a communications place or Tricky Dicky.
If it is a loose fit {In the swivel part} you can create static interference through your radio, you need a good connection.

If you want to communicate over less than 500km on HF, you will get as stronger signal if you tilt the aerial 45 degrees away from the vehicle.

Local signals like UHF CB travel in a straight line, so you want the aerial vertical to send as much signal as possible out horizontally.
For HF signals to reach beyond 50km, they need to bounce off the F layer of the Ionosphere, which is 200 to 300 km high. For the bounced signal to land within 500km you need to send it up almost vertically.
A vertical antenna sends minimal signal vertically upwards. By tilting the whole antenna or just the whip top, you are sending more of your signal up vertically.
For HF signals to go more than 500km, a vertical antenna works best.
