Post Should I buy an imax 2000?
Hi for HF I have been listening for the last few months on my IC725 using a full size G5RV strung from the chimney (which also holds my x300) to a tree at the bottom of the garden (about 105 feet). I intend to buy a tuner as soon as funds recover from Christmas

Anyway.. I've just been offered an Imax 2000 locally for £40. This would get me on the air right away and is tempting as I have a spare 20' pole, I am also tempted at having a go at making a wire dipole for 40m. A friend thinks I might be being a bit silly wasting money I could use towards a tuner, but I'm not sure the G5RV will work that well on 10m so the Imax might still be useful. What are your thoughts?

This is an old pic of the garden, my shack is directly half way between the chimney & the bottom of the garden so the ladder line from the G5 is straight into the back of the radio.

Thanks
Andrew

So I assume you want to use the Imax purely for the 10m, 12m & maybe 15m band only?
Well if the antenna is in good condition then I say buy it as for £40 your not shelling out a lot of money and more antennas as a back up the better.

With the Imax you might be better keeping it low and near to the ground if possible as from what I have noted from antenna theory is that low to the ground is optimum for long range DX work and when elevated up at height it will offer more of a local transmission radius. The Imax will I believe outperform a G5RV antenna which is a jack of all trades compromise antenna where as the Imax is a pure dedicated antenna.

Get the Imax Andrew. At the end of the day, you'd probably get your money back on it if you wanted to get rid. Okay, its money towards the tuner that you're going to spend, but will get you onto 10, 12 AND 15 (I think). Have a play on there for a bit till you get the tuner money together and have that up and the G5. It will outperform the G5RV on 10m, then you've got the best of both worlds once the two of them are up. Is it an option to extend the laddline off the G5 and make it into a doublet? Then, straight into the back of the tuner if you're looking at one with a built in 4:1. A lot less lossy than the G5. Or use an external balun if it's just coax inputs. Either way, best of luck with what you do :)

Thanks I think I will go ahead and pick up the antenna tomorrow :D I had planned to keep the G5RV as something to compare other antennas against when I get the tuner but honestly my heads all over the place at the moment so I'm not sure what will happen.

Many thanks
Andrew

Looks an ideal location and if it were me I'd opt for the G5RV due to it covering more bands without the need for a tuner. What's that hoop type antenna you have above your TV aerial?

Simple option may be to salvage what you can from the G5RV and turn it into a ZS6BKW antenna as this if built correctly will allow resonance on most bands from 40m and up!

Here is a link for your reference and you will see why it would be suitable for your self with out a tuner: http://www.w5ddl.org/files/Zs6bkw_vs_G5rv_20100221b.pdf

Looks like an FM radio, broadcast band, horzontal omni?

I have a Leak through line "Stereo" receiver at this end! :D
Its actualy an after market modded Through Line 3, with the change of valve, and factory fitted decoder! :good:
(So it still says Through Line 3 on the front).

SHOW OFF :rotfl: Mine's mono, sadly not getting used these days as the wife thinks it isn't pretty enough. Luckily my valve amp and speakers are still in use :)

To be fair its not the best Stereo decoder I have ever come across, it can be awfuly hissy if it isn't a very strong lock!
It spends most of its time switched to mono!
I always fancied a Through Line 2, the colour scheme is much better than brushed Aluminium! :D

Get the imax and you will work 10m 12m perfectly 15m may be a push without a tuner as i dont think it can cover the 5mhz plus bandwidth completely but once you get a tuner you can use it down to 20m.
And with 10m still open you will work some good dx.

For £40 (assuming you are on a Foundation licence) you should be able to buy a lower power ATU and have all bands via the wire antenna.
