[Elecraft] cobweb antenna

[Chris, G5VZ]

I don't know exactly what G3TPW is doing these days but M0ZIM is selling 
a commercial cobwebb: see 
http://www.mcr666.com/sales1/ham-radio/4-meter-70-meg-base-vertical-antenna/cobwebb-antenna/

Usual disclaimers - I do have one of these antennas but otherwise no 
interest in the operation.  I think Mark will ship worldwide.

So I sent an inquiry via regular mail, including a self addressed (with postage) return envelope......no reply whatsoever.......

But back then I was doing more portable ops and since the commercial version is more sturdy I decided to get one......saw one being offered on ebay so I bid and won the auction. Eventually I lost one small bit and needed a replacement part so I contacted W3FF and got very fast response....even though I hadn't purchased direct from them.
