Guys, I couldn't locate my schematic, but here is one that is exactly like mine in all respects: www.k5ua.com/technical.htmIf Pete builds one of these things and uses it with his Imax verticals, he'll be the new channel 13 and 10 Mtr GUN on the block  . 73, Randy AB5NI |

Now I need an antenna tuner for parts....shame I didn't see this before last sundays' hamfest. That is a project I would like to apply to my 40m ground mounted vertical with a second antenna.

Spitfire 441 (aa3re) Glad to here it, Pete. The great thing about an LC Phaser is that you can use it on multiple bands, although you'll need to have the proper antennas along with proper spacing. That being said, it should work like gangbusters on your Imax setup on 10 and 11 Mtrs. All you have to do is tune down (null out) the stations you want to work, flip the switch, and you'll have maximum signal going their way. You'll also be able to "steer away" from bothersome skip and attenuate those signals significantly. 73, Randy AB5NI |

The Idea of using phased verticals as a "beam" has always facinated me. That is what led me to the Hy-Gain co-phaser. But it does have its limitations as far as 'steerage". I live in the forest so long high mounted yagis are out. That has led me to alternate ways of getting gain and nulls. It really came in handy when we had a local knukle dragger and he happened to fall right in the null. I could wipe out his 20db gain garage amp with the flick of a switch. Ha ha ha. 441 |

Ha ha ha. 441 You will not be disappointed, Pete. You'll sing its praises so often, you'll feel obligated to send me your J.C. Penny Pinto SSB rig! (Just kidding! ). I'd love to see Night Ranger build an LC Phaser and a second Lazy H and blast into CRR, too. He's got the room for it for sure. The theory behind the the LC Phaser (and delay lines) is that one antenna gets RF before the other and establishes an electromagnetic field, and once an electromagnetic field is established, they don't like to change. Along comes the 2nd (delayed) RF signal to the 2nd antenna, building up its electromagnetic field, and when it brushes up against the first established field, that field says, "WHAT?! Get out of my face, or I'll b*tch slap ur ass into the next universe! " and the 2nd field is pushed/distorted away from the first field. The distorted field/antenna is the "direction" in which you'll have directivity and gain. Well, it's a bit more complicated than that, but u get the idea. Note that both of your feedlines to each antenna should be an electrical 1/2 wave in length (or multiple if they can't reach the antennas), and the lengths of each feedline should be as accurate as possible. If I remember correctly, you can use an antenna analyzer for these measurements. (Alas, diabetic strokes have taken some of my memory, and I'm not the man I used to be intellectually. I constantly second-guess myself because of fragmented memory  .) It is also important to note here that you do not need to use the hermetically-sealed relays like K5UA used in his setup. You can easily get by with a heavy-duty DPDT switch. Remember that you could be switching large amounts of RF around, so please don't use something cheap. OTOH, that is a great switching system he's using, but it does add a bit of cost to the setup. (Shrug.) Anywho, I"m glad that I could pass this info along to you guys. My antenna mentor, Jerry, W8HXR taught me this stuff as a kid, and I'm just paying it forward and passing it along like he did. I only ask one thing: every time you notch some buttwipe jamming your signal or you're 20 over on someones' meter, you stand up, raise ur hands above your head, and bow at the hip toward Cajun Country and say, "May the RF God bless you, Zero Five Coon!" . 73, Randy Zero Five Coon |

"May the RF God bless you, Zero Five Coon!" . 73, Randy Zero Five Coon There's only ONE Zero-Five, and that's W8ETS, aka Gene, AKA Firestarter. |

LMAO!! I have to agree with you on there being only one Zero-Five, SB. . 73, Randy AB5NI |
