Re: Improving the Antron 99?

I am looking at possibilities to get antenna location changed to allow for possible radial.
I will look at the siggy 4copy too.
Back in the day a friend used these and it truly was fantastic apart from the gamma I recall suffering from coming adrift or loose ?.

The old faithful Antron looks better than ever with some 3 coats of fibreglass resin sanded between coats then baked hard via the fantastic sunshine we recently have here.
As the resin has no uv resistance I purchased a uv resistant yacht varnish of which another 3 layers will help protect it.

Paid particular attention to the adhesive that hold the glass poles in to the end fittings with the resin to add durability .

It will go back up for a while but I will continue to push on for the upgrade.

Still considering insulating the antron from the mounting pole and maybe a few radial wires at a angle dropped from the base and maybe do away with the air choke . But again I welcome your collective knowledge on what's best. However I don't cause tvi either yet.
Thank you again .

I should think that with all that varnish, yous will be the last surviving A99 and will take centre stage in the main hall of the CB museum!

Maybe they'll drill through the resign and extract the essence of an A99 and create A99 world as a Theme Park :-D

Lol, well I'm hoping it shouldn't effect the antennas working as it has no metallic in the coatings.
Seems to me like with everything else those glass fibre antennas lack a proper protection from de lamination and uv.

I may treat it to a few coats of heavy Sun tan lotion too ,wonder how that would work. If you have ever got it on auto paint finish you will know how hard it is to remove even years latter..

I wonder if theirs anything that can be put on alloy antennas to save them oxydysing too..

Probably snap when I get my mate to 're install it .
I could just bury it in a time capsule lol.

Lets be honest, they all end up in the same place eventually....

You can buy an anti-corrosion grease, I believe from the US. Not sure on price though. I think it was for use on boats etc originally.

It may however gather a fine layer of dust if it remains tacky.

BTW, the aerial I was thinking of was the Vortex Q82 Mk2...looks rather like a Sigma 4 and should be pretty well built.

Will look at the grease and vortex antenna.
I have used protective grease sprays on motorbike parts that are prone to rust if ridden in wet weather and that worked .
I've used hairspray too but isn't very lasting.

Out with the autosol and cloth it is then.

The Vortex antennas are very well made, but they are also seriously expensive.

You could get through 3 Sirio 827's for the same price, and overall performance is unlikely to be much different.

There is no such thing as a Fidelity 1000 which is too good to scrap.

I guess simon that is a big part of it the cost. If I were a regular radio user and twas my main hobby I could consider spending more maybe but its not.

You raise a good point too in that despite its well or even better made doesn't neceserrally mean it will perform any better.

Would be fantastic to try all these antennas in a real world no bs test.
Same feed radio and position.

I'd still love to try the sirio gpe 27 5/8 against the eurocom hygain silver rod type too.
And then replace or lengthen the radials.

I have no doubt the sirio will perform better as is but with longer radials ? .
I'm still not Keen on the amount of joints between the plastic and alloy on the gpe either and unsure if in sunlight the coil housing will condensate up too .

I think the more I look though the gpe is the value for money better material antenna.

If you put longer radials, you have to shorten radiating element, that gonna change elevation for worst in most cases.
5/8 antennas does not need long radials, because maximum current is located higher than radials are mounted.

Thank you Chris, so what's your best suggestions for a vertical antenna 5/8 preferably that will improve over the antron on rx tx signal .

Decent aluminium antenna have radiating element close to 5/8 length and it is electrically extended to 3/4. It gives best elevation.
Sirio 2008 or 2016 for example.
Sirio 827 is worth considering too.

827 will make a BIG difference to an A-99,look for a localish secondhand 827 on the tree of gum/put a wanted ad on.The A-99 will do the now ;)
You can talk worldwide on CB radio = not 10 - 15 miles,
some are too far up their own @rses to admit it = snobs,
many freebanders just happen to know otherwise = 27Mhz.

I use a Sirio 827 about 4mtrs off the ground, works a treat and makes an A99 look like a wet piece of string performance wise.
It's also a great vertical antenna for tuning on Amateur bands from 10m - 20m
