Default Using a discone without all 'arms' attached

I have had a discone antenna for about a year but I haven't gotten much use out of it because I don't really have space to mount it inside my attic and doing it outside is not doable for a variety of reasons. I was recently thinking: would it work to simply erect the discone inside (in the corner of my office) and not have all the "arms" attached to it? I obviously wouldn't get as good performance out of it, but I would imagine that it would be better than a rubber-ducky antenna.... I just want to make sure it won't be harmful to any of my equipment. Any thoughts would be appreciated!

Thanks!

Dan, kc9vzv

Ok, thanks! I'll give it a try.

I assume you are talking about using the discone with a scanner for receive only. Unless it falls over on your FAX and accidentally sends a message I don't see any way it could be 'harmful to your equipment' since it is not radiating any energy.

Good point! If it falls over at all, we will have bigger problems than sending a fax accidentally!

I'd be interested in learning how a discone would do without its groundplane.

I'll let you know once I try it!

This one works quite well:

The Hustler is particularly poor at 700/880 MHz due to the too large spacing in the separator between the disk and cone--keep in mind its design predates those bands. It may work work better at low band VHF but I use better antennas there.

I agree 100%. It probably doesn't even qualify as a Discone.

With an antenna switch doing an A-B comparison between the DCX and the Rat Shack discone the 20 year old DCX gives consistently higher S meter readings on V-low, V-High, and UHF. I don't have anything on 800 with an S-Meter. The DCX has survives winds that have left the lower Rat Shack elements wrapped around the Mast or missing.

Did I mention it cost about a third as much?

It has done me so well I bought another at AES last trip to Las Vegas.
