I think I have a problem on the 28MHz band with the homebrew Cobwebb that I
have made.

The SWR is 1.1 and is tuned at 28.500MHz.

If I listen to this band it receives strongest at 28.500 and drops off
sharply after about 300KHz each side along with a rise in SWR It can reduce
a S9 signal down to S1 on both sides.

Is this how the Cobwebb performs or is there some thing wrong with it?



I like to listen to a few people on 27MHz that I know. They are only 5 miles
away. I have no problem hearing them on a G5RV but I can only just here them
on the Cobwebb.



Many thanks

I have some questions about the choke and feed line on the Cobwebb.



Does the co-axial choke balun work better if the cable is wound on top of
each other into a tube shape rather than just winding it round and zip
tying it together in a round bundle?



Can I attach a SO239 Chassis socket to the end of the box where the coax
enters and then plug a PL259 into that for the feeder or will the socket
allow current to bypass the choke balun and enter the feed line?



Thanks
