Hello,
Throw as much wire as you can up in your loft, feed it in the center with ladder line to a tuner. I used one for years. I called it a "Dog-eared dipole" because I let the ends just droop down and along the attic floor when I ran out of attic length. It was cut for 40 meters (33 feet per side) and worked good enough. Since it's a balanced load, I don't have any trouble with TVI, but it does get into the telephone sometimes. I just used a staple gun to get it as high as I could. Good luck & 73's KD5ZCL Robert Lay wrote: On Mon, 3 Jan 2005 15:16:53 +0000 (UTC), "Simon Smith" wrote: I have been refused permission for any kind of outdoor Antenna due to the area in which I live in the UK having "permitted development rights removed" I think that this may be a conservation area. Having recently passed the foundation course I am getting impatient - and dissapointed to say the least. I am now faced with only one or two alternatives - an Indoor or Loft Antenna. I realise that this may restrict me to 2m only but at least it will be better than nothing - or to operate mobile only. Has anyone on the group got any suggestions ? I have a fair sized loft with approx. 2.5m headroom, which runs the whole width of the house -almost 30ft. - is there anything I use in the loft like a loop Antenna for instance ? Or a fixed Station Antenna ? Thaks for your help John M3IIV Dear John, It has been my experience that the inefficiency of loft antennas make them nearly useless. However, you have to work with what you've got. My suggestion would be to build the best 20 meter dipole antenna you can build for the space available. Try to keep the ends of the antenna as far away from anything that absorbs RF as possible - even wood and brick do absorb RF. If necessary, use loading coils in the dipole to get the dipole resonant (at 14.070 MHz). Think about PSK31 as an operational mode because that gives you the best bang for the buck in terms of being heard 'round the world and being able to hear others in adverse conditions.
