Improving the Antron 99?

Post by original45 » 16 May 2018, 14:45

once my antron is treated to a little tlc it will go back up until I can decide on the next upgrade antenna and purchase it.

As it was it was up on a galvanised pole some 11feet long mounted just under soffet boards on house wall.
Fed by rg 213 8 turns on 6" choke.

I'm wondering a few things.

Firstly will I get a benefit by removing choke as it makes little to no differance anyway.

Should I insulate the antenna from the pole.

Should I fit a counterpoise wire from the base of antenna to try to match it ,I'm thinking 20feet long ? And angle it's position away from the feed coax to reduce and problems .

Has anyone made any improvements worth me trying .
Thank you

The best thing you can do with an Antron to improve it is get another antenna.

A 5/8 wave might only have about 1.5db gain on paper over the A99 but in practice the difference is usually greater. Oe or two S-points on both TX and RX being common.

Metal antennas also bring in less noise generally.

No improvement from the antron to IMAX 2k ?.
I give up, can't have a beam up here .

It seems to me no one makes a very good simpke antenna
Too longer radials for most installations. Water ingress in to coils. Cheap crap alloy tubing that's flimsy.
Poor thin copper coil wire internals .
If I lived in the states I'd buy one of big hairs antennas or IMAX upgrades with silver coated heavy copper wire.

Dv 27 on a biscuit tin with radials anyone ?

Double bazooka, simple as they come, cheap to buy or make, low noise...

My A99 is ok for a mobile DX antenna. Quick to put up, no need to SWR, quick to take down.

Other than that it stays in the shed.
Never, ever, ever....bloody anything ever!

Far too many radio's to list here. But I do own a legal one...

I will look again and do more research, I'm realizing slowly that unless I buy all of the big vertical antennas set them all up in the same position ,same radio feed I may not find which will be best.

I had initial issues with Antrons set but resolved it but it was cheap and in ok Nick.
. Whilst I'm not so knowledgeable in radio com I have found the Antron solid,reliable very very simple and pretty good over all in tx rx signals up to 18/20miles.
It isn't far off my old gap 5/8 that was up some 40feet in the 80 s with crap coax.

I get about 2s points of static noise but that's hardly surprising with the amount of electrical items the neighbours use today.

The Imax I do like the look of simply because it will be simple , likened to the 99 the tanks like them anyway.
It is longer than most too and is a little more than a 5/8 wave I read.

I am very put off by the issues of water in sirio coils ,the complaints are endless.
I may have problem with mounting antenna with radials too.
I would have preferred a alloy antenna this time for weight .

I am naturally a person who had difficulty making decision "Aspurgess" and social anxieties but I hide it very well and have worked hard to overcome big obstacles in life hence my constant need to ensure I buy right first time , it can stop me dead in my tracks too so that added to the lack of radio knowledge I have isn't ideal

I do appreciate your advices and help even if I don't understand all the technical occasionally.

Back to my search for now to find a better performer than the A99 that suits preferably a 5/8 without stunted growth
Think this is hard trying to buy a antenna, it will take me Yeats to buy a ssb radio.
It's been a year now easily.

Thank you for your patience and again for your collective knowledge and experience .

The IMAX should work better than the A99, some people who have used them mention a single S-point improvement. I think the design is compromised by not having radials, hence why a metal 5/8 like the Sirio GPE, Tornado, 827 or 2016 should work better still. Trouble is that radials can be an eye sore.

Get one of those well-made Sigma 4 copies that Dave "Oggy" reviewed a while back. Can't recall the name if it and not sure on cost though.
