I won't convince you, but I had Imax, A99, Shakespeare big stick along with nice aluminium antenna on the switch for a long time.
Difference is easy to notice. Try yourself.
Try it myself? Well funny you should say that as I had a Sirio 827, Sirio Gainmaster and an Imax 2000 up all at the same location and the Imax won the battle hands down. If I moved location maybe the Gainmaster would win or the 827, Who knows. But I do not come on here saying that's crap and thats crap, Why? Because I grew up a long long time ago. Different antennas for different locations, Go figure.

I don't think there is any definitive advice anyone can give on what antenna is best, different situations, different antenna, different results. If you're out in the sticks 1700ft ASL with no noise then you could get around the World on a wet bit of string up at 10ft but if you were in a deep valley with hills all around you could have a 4 ele Yagi 80ft up and maybe transmit and receive 50 miles or so, so it's a question of where you are located, what you have around you and any physical and other restrictions as to what antenna you can put up. As for noise giving you an S5 or whatever, you will not get rid of that no matter what you do, it's usually what's around you that's the cause, such as security lighting and or any other LED lighting that uses cheap Chinese transformers to power them, central heating motors, broadband routers, PC chargers, the list goes on. The best antenna in the World will do nothing for you if for any of the above reasons you can't use it.

37 years I've been in the radio hobby and I've tried all sorts to see what's best.
Some dead certs simply don't work in a certain environment or under certain conditions. For HF Amateur Bands, I've had everything from a dipole to a 5 element tri-band Yagi and under certain conditions, I've questioned the Yagi.

I've had several verticals for 11m and I honestly don't see any huge differences in any of them, at least not that I would stand back and shout from the rooftops.

Thing is, it's a hobby and we are all meant to experiment with stuff. Folk have different goals and expectations. It's just so disappointing and bl00dy annoying when you get folk who think they are the foremost authority and they know best and ridicule others.

Knock up a quick dipole use a chock block connection block string it up and try it very little work just as a quick test and judge if its worth making it waterproof and permanant

Don't forget to strip off all the insulation and then polish it to make it sparkly cos all those radiowaves are like magpies, attracted to shiny stuff and once you've done that cover it back up in insulation because leaving the insulation on is a sure fire way to make it not work unless it's special radio insulation cos it says so in a special, out of print secret German book that's too involved to explain to mere mortals who have CB antennae that work 'against all science'.

It's the little things that make all the difference and all those hams and antenna professionals and designers over the years must all be wrong cos the bloke on 27.245 sez so.

Or grab yourself a load of wire, some choc block or a dipole centre, use a web calculator, add a few inches to the result, cut your wire to length.

String it up, measure the SWR, if it's high, fold equal lengths over on each end, cable tie it up and measure again, repeat until you get a decent SWR.

Most of all, have fun experimenting, make notes, think about it, learn something and ignore pillocks on forums who think they know it all (that includes me).

Well first of all thanks to all who answered my question,having considered all i have ordered a doublet dipole antenna and a 1-1 balun , It is 10 mts long each side with 30 ft of down lead to a 1-1 balun then my mini 8 coax, The centre of the inverted V will be 45 ft high How dose this sound to you ???

Sounds like antenna not for 27MHz.
Can we see how's balun made?

Hi chris ch25 lets see what faults you find with these items = on e/bay item numbers- antenna= 322402789514. balun = 322624955738 Are these items any good ??? I know they are not just for 27 mhz but who knows what my needs will be in the future,

This antenna works only with antenna tuner. SWR will be higher than acceptable. For CB/555 you can easily build that by yourself with our help.
Balun.... there is no information about ferrite toroid material is used. We can assume that might be proper or improper core material.
I suggest to DIY http://www.qsl.net/dk7zb/Baluns/current_balun.htm

Of course you can try that doublet on 27MHz, but I'm more than sure it won't work as good as resonant dipole cut to proper length.

They'll both be crap compared to your Imax 2000 at a similar height.
You talk crap.I had a 1/4 homebrew dipole 15ft lower than the 827 (30ft up) and it could hear Scandinavia no problem,the 827 couldn't even hear it,nowt to do with what's the better antennas,just that 1 was in the best position and the other wasn't,and it was a new 827.Last summer I was far stronger to the op Trevor in Swansea on my homebrew dipole than the same 827 when again it doesn't mean the 827 was crap,and it was a Harvard homebase 407 + Rmkl203 end of scale,then 4w a 9,then 0.4w fm and I went down to a 7,with same dipole 15ft up....works out pretty far for a CRAP homebrew dipole....some folk sit a test and think they are doing well with 10w on 40m getting that far with a £100 dipole.Thats why I prefer (C)heaper (B)roadcasting.



Ch25,just for the record I also use an Imax at present,not the best Cb vertical but I wouldn't say it was total crap.Next you'll be saying the TS 590 is crap.And before you tell me to use better radios than a sh1t Homebase,I have tried many Hf rigs,old school Cbs and most of the Chinese/President sh1t they sell now.I just prefer old school radios as I prefer an analogue signal needle on the meter.I am using an At5555 at the present time,only because I got it with a mint Sadelta desk mic (swapped it for an Audioline 341) + Opek power echo mic for £60.My opinions are based on what I have used, not what I've read on here/watched on utube.I dont know much about radio but I know that it costs a fair bit to have a "real" opinion.
You can talk worldwide on CB radio = not 10 - 15 miles,
rsgb are just too far up their own @rses to admit it = snobs.

I use a Dipole which I made for around £10.

I have one facing North to South and another facing East to West.

I have worked all over the world when condition are in my favour.

I always getting glowing reports and great feedback on the wire.

It all depends on what you want out of radio, I rarely use the FM mode, good job too as the dipole really is not suited and of course directional.

Regarding the Imax, I owned one a few years back and I must admit I was very impressed, worked very well, does not look too much on the house like a 827. I would definitely buy another without doubt. It was mounted well above the apex, bracketed with scaffold bars. Its all in the setting up, get that right and you will bang out I can guarantee that, unless you live in a Valley that it. :D

Not a fan of the Imax.....Its worth giving the dipole a go try it in an inverted V configuration you will be howling when you've worked a few stations on your homebrew simple as it gets aerial. I've read a few things posted by ch25 and sometimes he comes across a bit brash but everything ive read as been spot on....so good advice.
