Post qustion for steve
i have very limited space in back garden, at the minute i am using a home brew inverted L for 40 and 80m, due to the limited space i have put a hme made loading coil after the 40m section, fed from my at-230 long wire connection, this seems to worrk reasonably well on 40 but not so good on 80, space i have available is 22ft vertical and 28ft horizontal, could you suggest anything better for this small space, have searched the net and they all seem to require about 67ft

cheers dazza

take out the trap and use the space u have in the inverted L configeration,and use a remote tuner at the base this will keep your losses to a minimum.

i have used a 7m fishing pole with around 40ft of wire in the inverted L configeration with my sgc-230 at the base and worked a lot of stations from 80m-10 just portable, u just have to make sure is u have got a very good ground.

An Inverted-L is a pretty good choice for your situation, and a total of 50ft can be made to work OK on 80m. But you do need a good ground system.

Does the Inverted-L wire come all the way back to the tuner, or is there a length of coax between the two?

Post Re: qustion for steve
you would notice a big difference if u could put a tuner at the base of the antenna.

im sure steve would agree

ive tried lots of different antennas in my short space i got,and tried endless times with homebrews but i cant better the inverted L with the tuner at the base with radials, i can even get contacts on 160m but from 80m to 10m performance is very good.
if u can get everything right i find the inverted l a very good performer and hard to beat if configered correctly.

hope this helps

Then it sounds as if one end of the Inverted-L must be close to, or inside, the shack/house; that may result in some screening of the signal.

Also - because you are getting better results on 40m than 80m - you may be suffering the effects of a poor ground system. On 80m that length of wire will need a very good ground; on 40m it's much less critical.

As Billy said, the ideal would be to get your Inverted-L in the clear, feed it against a good ground, and use a remote tuner. There's no reason why a total length of 50ft shouldn't work well - even on 80m - if you can engineer a good ground.
