bolt and play and seem less affected by conductors around them. The 340N will have a tighter pattern, better f/b, with better rejection of off-pattern QRM and QRN. ANY 2 element yagi has theoretical limits to it's pattern. With the ocean to your rear when you are pointed to EU and Eastern USA, the f/b may not serve you as well. Here on the east coast, the rest of the USA and SW thunderstorms are off the back and side when pointed to EU and the 3 element qualities are valuable. Another reason for the 240N/340N is that they have far less of the tribander 15 meter suckout phenomenon. The folding of the elements moves the secondary resonance of the beam elements off the 15m band. The 240x seems not as clean on this. Good luck, Guy. ----- Original Message ----- From: "Kevin K7VI" <k7vi@arrl.net> To: <force12talk@qth.com> Sent: Sunday, August 04, 2002 10:58 PM Subject: [Force 12 Talk] Which 40m antenna? Hi, folks. I¹m looking for your opinion about which F12 40m antenna you¹d recommend. My situation is a 120¹ tower over flat/sloping-away terrain with just a C31XR up there. I work predominantly DX and DX contests mixed between CW and SSB with a bias toward CW. My 40m work is almost exclusively CW. Perhaps I should ask my question differently, so that the answer isn¹t unanimously the MAG-340N! Just looking at the specs, the EF-240 or 240X look very compelling from a price/performance point of view. So maybe my question REALLY is what is it about the MAG-240N (yes, the two-element version) that would cause you to spend the difference in price from the EF-240X? I¹m not inherently bothered by the price of the MAGs. I¹m simply trying to better understand the choice. Many thanks.
