No worries Gaz. Prob not a big deal if its incomplete / unservicable.

There are a few people here who are restoring vehicles who may pay decent money for a working unit. They are not the easiest items to obtain.

Those doing this may be interested in the RFI CD991-67-73 as it covers the full band from 400-520MHz. This means it can be used with virtually all Australian UHF services including Amateur, CB, SES, RFB, Police and commercial. Combined with a radio with, e.g., coverage from 430 to 480 MHz it gives a single radio solution.

Gday Diana Alan I would be interested in a look at the finished product.
Thanks. Paul.

Hi Howard, very interesting. I just googled RFI CD991-67-73 and there is only one mention in the whole world - yours (above), 4 days ago.

"Combined with a radio with, e.g., coverage from 430 to 480 MHz it gives a single radio solution." What would be your recommended radio?

Yes. i emailed RFI about having another of their antennas tuned to cover frequencies I want and they came back with this one. I have now bought one and it is a solid piece of kit: it will look ok mounted on a sugar scoop.

As for radio, I think the WM9000plus ( http://www.409shop.com/409shop_product.php?id=108685 ) would meet most requirements.

Hi Carzee

The antenna is easier to find if you go direct to the RFI site and search the antenna from there ( http://www.rfiwireless.com.au/broadband-uhf-elevated-feed-antenna-cd991-67-73.html )

The antenna however may look a little out of place against a AS1729 as its a little less than 18" long.



The radios it would work with are:
UHF-CB,
Amateur (Ham) radios in the 70cm band
Commercial licences

Hi Paulak

Currently I am only doing a small batch because of the costs to me, about half of the 10 have been allocated.  They won't be cheap as I have been quoted about $150 just to make the mould, the alloy disks are $8, the alloy tube hasn't been costed but add a couple of dollars and then the welding and tthen there is the resin and fibreglass or the cost if they do it for me.

What I am after is the cover ring over the bottom flange of the ATU.  These will be discarded when ATU break but will cost heaps if I have to make a press mould or spin each ring individually.

Will let you know when they're finished.

Actually they are not selling that one now but the TYT9000 plus is identical (the WM was a rebadge)

Hi Howard

Back in June I contacted RFI about the possibility of having the CDQ5000 or the CDQ8000 (5dbi or 8dbi gain) refinished in khaki, but they would want about 50 ordered before they even considered it.

I thought for our purposes the CDQ5000 etc, were a better option than something like the CD991-67-73 because most of our members don't have Amateur licences so an antenna tuned to the UHF CB frequences more appropriate and also that the stick is over 2m long so similar in length to the AS-1729 also with a detachable stick leaving the spring base just like on the MX-6707.

Diana

Good call Diana. In my case I use it for amateur, Rural Fire Brigade and CB.

By the way, I applied to ACMA for a frequency around 46MHz for our Club with the idea we could use ex-mil gear for club comms. Unfortunately they were willing to give us a frequency but only in VHF or UHF bands.
