Hi all,

I would like to know what brand and type of UHF aerial the readers of this forum are currently using or recommend. I have in the past had 2 6Db non-ground independent aerials (Mobile One) mounted on my roof rack, these gave excellent range and reception but after snapping them both on trees and my garage (forgot I still had it on and parked the car...Doh!) I have decided to try a ground plane independent mounted on my roo bar. As such I would like to know what you guys recon is a good buy...must be 6Db, ground plane independent...

Cheers
Grazza

Benelec, GME, RFI and several other companys all make good ground independent UHF-CB antennas.

The type that I prefer has an approx 8 inch chromed base with a 2 foot whip. The wire whips eventually snaps off at the base so get the fibreglass core whip - about $75.

The higher gain you goto the more you flatten the radiation pattern; good for flat land range but reduces up and down into valleys etc. Most of the whips about are 4.5 db gain.

Grazz, I run a spring-base 6 db centre-loaded 600mm, mounted on the top tube of the bull bar and have no problems. It's a ZCG and so taller/longer shafts are interchangable. It was around the $90 mark.

In the 6 dB the POLAR is a good choice (get the model with the spring included). GME and RFI are always a good option too.

I've got a POLAR 6dB on one vehicle and a 4 year old GME 4.5 dB on the other (still waiting for the stainless whip to break like everyone said). The 6dB is definately better for distance in the flat country.

Nigel, We've had 2 stainless whips break, one on a Cat loader, and the other on a Toyota DA115 truck, both have a big vibration problem! These days use 6dB kevlar (?) whips, though did get good performance from Polars. They would be the pick of those elevated gain aerials. Regards....

Kevlar? That would cope with anything... Might have to hunt one of those down, coz my s/s one's gotta break eventually. Maybe GME used better s/s than other brands.

Nigel, FYI. Kevlar whip is Antenna Agencies P/L (Ph.0755233388) Model CB6 Deluxe. Cost $85.00, for whip only, spring base mount adds a bit . Don't think we've broken one over the past 2 years. With the original fibreglass whips, you could lose a few each month!

Grazza, reckon we've used every aerial made over the last 20 years, and think the Polars would be one of the best 6dB available. We use to mount them on a home made bracket that bolted onto the top mount of the snorkel on 75 series L/C's. Now use 6dB whips mounted on b/bar. Currently have one of the GME interchangeable whips on our wagon, 6dB for local trips, 4.5dB for trips to coast and a smaller one again for when in the big smoke. Bit expensive to set up with the different whips. Reckon they are like tyres, everybody has a preference. Catch you later...
