I am a relative newbie to the world of SW.

I've just taken possession of a second-hand Kenwood R5000 comms receiver.

It
looks like a very nice piece of kit. It's not really practical for me to

rig
an outside antenna system at the moment, but I have heard that you can get
SW antennas designed for indoor use. Can anyone recommend any? I am in the
UK.

And if anyone has any thoughts on the R5000, feel free.


Thanks to Dave and RHF for your informative and helpful replies. One
question to Dave - I realise this will may seem a silly question but why do
you use two aerials? Do they have different characteristics, or maybe you
use them for different frequency ranges?

Radiohead.




I currently have 15 aerials/antennas - 5 in the attic, two on the
chimney, three on the tower and rest sort of spread-around the yard.

I use them for different frequency ranges and radiation angles - short
range HF is best at high angles whereas long range HF is best at low
angles of radiation. 7 are transceive and the others receive only.

Actually I have 16 since one feedline also has a relay box to select a
short whip or a horizontal wire. And mine are all pretty simple ones,
none-of the really complex high gain stuff that people with lots of
space can install.

Antennas are fun and challenging, easy and cheap to make, arguably the
most important single contributer to a communications link. Improvement
to your antenna system will almost always far outperform any improvement
to the receiver that you can perform for the same amount of money and
effort.
