UHF arials for the bullbar

5w is the legal limit in Oz!!!!

Are you trying to tell us all you don't bend a few rules , I take it you do not do 70 Ks in a 60 zone, 90 in an 80, I run 27mhz from the truck when outback at 200w on SSB for a couple of years until I cooked the Linear, but then I do agree to a certain extent 25 w on UHF is a bit high, I think 10w would be ample ,
What they don't know don't worry them ,

Doug,

Someone much wiser than I am has said that rules are for the guidance of the wise and the control of fools. I reckon most of us here would not consider ourselves fools!

I'm also a firm believer in the principle that it's easier to get forgiveness than it is to get approval!

I see no moral objection to radiating lots of watts out in the sparsely populated areas. At UHF it won't go beyond the horizon and there aren't many people in between. Those rules are made for the urban majority.

The real issue is, as you say, "What they don't know don't worry them". A public forum like this is not a good place to discuss our misdeads, and I reckoned maybe Qubert wasn't aware of the rules.

Same as what we use. Had it for 6 years and never broken. Range seems to be OK. Done a lot of corrugations.

Ditto with Doug & Stevesub.

Fred

yes those are the best value

Thanks Doug, these dont seem to suffer from stress?? Do they ,mount to a UHF screw in female plug (sounds like im talking about other things hey) or do they use thesame base as a 27 meg??

I have mine as Raised feed , but yes it could be mounted to a normal base

Normal base Mounting

"A single antenna that uses a metal area under the antenna for the ground plane"
Monopole antennas require to be mounted onto a Base and need at least one square metre of metal as a ground plane to work effectively, this ground plane can be a Bull bar, roof, Balcony railing, any metal surface area. Monopole antennas are low profile, easy to install, they are available in various colours and do not need tuning.

RAISED FEED

Raised feed antennas can be used in any and all applications including base station
Raised feed are really a simple dipole made up of a monopole antenna and a ground plane
in the form of a 1/4 wave long tube, this tube draws the radiation pattern toward itself producing
a lower angle of radiation that hugs the horizon more effectively producing extra gain.

Thanks Wayne for your input. found one on ebay, and yes it would work well for the red flag :)

Does this look like what you own??
Thanks for your input

It looks like the right base but that aerial is shorter.
Mine is 65 CM long for the aerial alone.
21 cm for solid base EXCLUDING spring.
Price seems good.
