Since my ocfd has a balun I have thought that a common mode choke would not be necessary. However some articles that I have recently read may indicate otherwise. Does anyone have any information that can clear this up. I realize I can wind one easily enough, but since my antenna does not have a support there I don't want to add any weight unnecessarily. Does anyone have any more information about this? Thanks Paul W8SBH

#OCFD,

Since my ocfd has a balun I have assumed that a common mode choke is not required. I haven't seen any common mode current back in the shack Some articles that I have read make me wonder if I should add one. I can wind one but don't want to add the weight since I don't have a support at the junction on the antenna. Paul W8SBH

Added an ugly balun air coiled with RG213 7 turns today. Put this on an Antron 99 and it seems to be working well. Anyone else use these?

Cobweb antennas

I've searched the groups for one discussing cobweb antennas for HF -- preferably home-built and kits. Is there one here? If not I will start one.

So, I built a 2 meter cubical quad antenna. Recently, i took some measurements with my nanovna. As you can see the SWR is a little high at 2.42, and the reflect is about 20% with 80% of the power making into the antenna. The ohms are at 49.5 almost 50. I'd like to improve these numbers as I am using a handheld, if anyone could suggest some tuning methods I'd appreciate it.
