I have tested and compared it at a friends house who already had a tweaked and fb working two phased RX verticals set-up and the MFJ-1026; the NCC-1 proved to be much better in respect.<br />But I'm still having trouble finding a suited location on or near my small home QTH for the second vertical. Perhaps it will be a front and backyard vertical set-up with 20mtrs distance in between as I have found no better alternative yet.<br />Hope to finalize that proposal before winter sets in. I sure will write an article on my findings afterwards.<br />About the NCC-1; I would sure purchase it again!<br />'73 Mark, PA5MWMark, PA5MWhttps://www.blogger.com/profile/17075619376682529883noreply@blogger.comtag:blogger.com,1999:blog-5182520086776309209.post-55469195042833170002009-08-03T02:01:42.990+02:002009-08-03T02:01:42.990+02:00Hi Mark!

Given your experiences, would you purchase it again. What do you think?<br />73<br />Lou<br />W1AAJAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5182520086776309209.post-46333522283197420642008-04-07T22:51:00.000+02:002008-04-07T22:51:00.000+02:00Hi Mark,Dit is precies wat we zochten voor de 2x s...Hi Mark,<BR/><BR/>Dit is precies wat we zochten voor de 2x sloper @ 4tue. Zelfs mute schakeling is voorhanden bij zenden? Ik ben heel benieuwd hoe dat kastje werkt in contest op 160m @4tue.<BR/><BR/>Gaaf ding!<BR/><BR/>73<BR/>AurelioAnonymousnoreply@blogger.com
