Indoor antenna HF

Post by G4YTI »

My home qth is compromised to say the least!
Ground floor flat, small room, no access to outside.
Has anybody managed to produce a hf antenna even nearly half decent for this type of situation?

Whatever you put inside it will perform bad. No matter what you buy.

What band(s)? It will narrow selection.
RX only or you want radiate some RF to your brain cells?

If you have manual skills build MFJ-1622 for pennies.
Coil is 2,5 inch diameter, 5 inches long, 50 turns. 1mm wire diameter.

Frying some of my brain cells was the hope, at my age there are few left anyway!
Just finished 20m spiral loop. Seems to be receiving ok but very narrrow band width.
Something that covered more than one band would be nice as well. I can always hope.
Have ft857 and mfj manual tuner to play with.

My first post on this forum :?

I'm amazed nobody has suggested a magloop, great for indoors as you're listening to the magnetic portion of the signal so you will get far less interference. I've worked all over Europe on 40m on mine (using an iCom 705 limited to max of 10 watts).
