I am wondering if a beam such as a Moonraker 4 or Maco Shooting Star, or any make or size for that matter, would work if you y'ed the coax and talked or received on the vertical and horizontal side at the same time, opposed to switching to either flatside or vertical.
Would it cause any wave, swr, or any problems?
Would it make any positive difference?

Kattracker,
Check out the link below.
It will allow you to run Vert or Horz or VERT & HORZ together.
And also give you an AUX for your Omni Antenna
One box does it all for you.
Sometimes you need both. If your SWR is set good on both Vert & Horz, you should have no problems.
If you have a set of Beams this is a MUST HAVE!

Hope this help's.

INTERESTING PRODUCT! Will this switch work with my Signal Engineering Lightning 4+ ?? You mention similar SWR on vertical and horizontal. I do not have a matching SWR. Whenever I switch from Vert to Horiz (or vice versa), I always have to retune through my MFJ-969. Actually, ... sometimes the SWR is below 2:1, but who wants to lose that reflective power?
What is that switch doing exactly in the combined position? Creating circular polarity? |

No,you need a special phasing harness to achieve C.P.,it just splits your signal between vert. and horiz.gives you a 3db reduction in signal strength and may double your swr,that's all. |

Hey Lon, I just went to the sight on this. Does this mean it would work with this PDL II Quad that I have? Of course, if I don't ever get it up in the air, then it would not make much difference would it? Anyway, the auxillary would be to hook up my super scanner to. Correct? Let's see. How many jumper cables would I have to get? Any one got any money I can borrow? Sorry, guys, two in college. Need I say more?

Keith,
Yes, it will work on the PDL II.
AUX outlet would handle the SuperScanner.
On my White Lightning 4, I use TWO 10' Jumper's of RG- 213 tied to mast down to tower with room to allow for turning and then connected to both VERT & HORZ RG-213 Main Coax's running into shack.
I also monuted my Rotor at roof level with Thrust Bearing IN Top Section of Tower.
This way I have NO Weight On Rotor and If I need to work on the Rotor Or Remove it for work, Very EASY to do.
I have all my Mast Pipe running up inside of tower and bolted together at Joint's.
The top section/piece of mast pipe sticking out of Tower has a Section of Black Gas Pipe I drove inside it, and Bolted for Extra Strength in wind.
OH, and I have TWO GREAT! ANTENNA MEN who help with all of this, CEF #156 Redman and CEF #159 Homeboy. I believe you talked with both of them on the CEF NET a couple of weeks ago.
They are Roofers by trade and a Major help to me as I can no longer climb.

I would love to see some pictures of what you are talking about in your tower and mast and antenna configuration! Did you calculate the extra vertical weight/forces of having the roter so far down in the tower? Is the tower resting on the roof or the ground?
Picture worth a thousand words.... Got any? |

Ca346,
Very Simple,
Rohn 25G - 5' Section in Concrete in ground 5' x 4' hole. with 1 foot of gravel at bottom for drainage.
Then;
5 - 10' & 1 - 6' Section of 25G to top.
3/16 Guy Wires at 45'
Tower also attached to Roof
Rohn Tower Plate and Thrust Bearing at Bottom Step's of Top 10' Section of Tower.
Tightened around 2" mast pipe running from Antenna Thru tower to Rotor.
Alliance HD-73 Rotor mounted on another Rohn Tower Plate at roof level.
This allows me / them to remove Rotor and Lower Antenna to top of tower thru hole in Base Plate.
By Having Thrust Bearing on Mast Pipe there is NO WEIGHT on the Rotor and having Mast Pipe run all the way thru the center of tower also give's added strength to tower in High winds.
I will send you the two Pictures I have of the SE WL 4's on roof showing Rotor at there feet and the other one will be Redman, At top of tower pulling them up to mount them, Showing Thrust Bearing and Tower Plate at bottom of TOP Section.
You will also see mast pipe running thru Center of tower to the top.
SE's are at 56'
The Picture's will not show all the Antenna's as they took the other's down to raise the SE's when they installed the SE's.

As stated in my e-mail to you, neither pic made it. I have NO idea why the pics are not getting here, but thanks for the effort anyway. 
I'll try and vision it...

I did the pipe inside of pipe deal too. Made for a VERY HEAVY piece of pipe to hoist up the tower. Although i had a bucket truck to help me out!!! |

Ca346 & RCI2990,
Poor Redman and Homeboy was adding section's to tower and carried them up by hand and when they got to my top Section of Mast pipe they almost died Pulling it up by hand and then Drilling through it.
They used 3 Re-chargable Batteries and then the 1/2 Inch Electric Drill to finish.
I even made a very NICE 2-piece GIN POLE for them and set it at base of tower.(looked good sitting on ground as they never used it.)
On above post I actually forgot to mention the day the beams went up we had 7 of us here, Me & 1st Sargant & Corn Cob on ground (for support & ground work) Raven, Beerman, Redman, & Homeboy on Roof & Tower.
OH, and a couple other's who drove by for added Support.
At one time Redman, Homeboy and Beerman on top of tower before guy wires were put up.
We pre- set SWR on SE's with them on top of 8' Step Ladder in back of my truck. Then I drove across street, next to house and they pulled them to roof and then UP they went.
The we used Yaesu FT-50R 2 Meter handheld's for Final SWR Settings, (Me in house with Radio's & Meters) and them on roof & tower.

It's amazing what we can do when we are excited about something. I planned for months before actually getting my tower up. I see a BIG difference in the DX now that I'm using a Lightning 4+. I can also always tell when I'm talking to someone that seems to stand above the noise. It's not always the bigger mouth (power). Alot of times it's the ears (Antenna). I had two guys on the ground when I raised my antenna.
I put a pully at the top of my mast before it went up, and threaded a 3/8" rope through it so I can pull light objects (My antenna) up and down. Works like a gin pole left in place.
Still no pics. Last two e-mails were completely empty..? |

Tech808, Lon:
Meant to ask you how you got the XYL to get into radio? It is supposed to be an old axiom (factoid) that 'opposits attract'. I'm the talker, my XYL listens.... Well some of the time... Actually, the only way I got a new Heil boom headset microphone through the bookkeeper, was because she figured how quiet it would be...well half of the conversation anyway...
It's a great hobby!  |

Ca346,
Back in the early 70's we had about 100 women in the Action City Breaker's CB Club we started.
Some Single and a whole lot of XYL's.
And that was just in our Club on 13.
There was also a Channel 1, Channel 3, and Channel 20 groups.
She has her Radio's and Equipment and I have mine, and then we have OUR's!
The 1st Sargant has been super nice though as she let's me use her radio & equipment for the CEF NET on Sundays.
I think, just so she can play in the Chat Room.

Re Big Bob Posting...
"No,you need a special phasing harness to achieve C.P.,it just splits your signal between vert. and horiz.gives you a 3db reduction in signal strength and may double your swr,that's all."
Hello bob...Bob is correct and I will elaborate. If you split your power if you do not feed the two antennas out of phase and pulse the signal.
If you put equal lengths of coax then both the horizontal AND the vertical with signal at the same time then all you acomplish is to apply half of the power to the mode being used by the other station. BUT if one side of your coax is slightly out of phase/longer than the other one you get a pulse effect with only one mode being hit at any given time.
Hams use this principle when they phase ground vertals so as to aim their verticals in a given direction.
Just for the data bases. Circular Polarization, which is what is being discussed, is used by hams to receive satelite signals. You see the satelite rotates constantly so the little vertical antennas go from horizontal to vertical over and over. The output signal may leave the satelite as a vertical but due to spinning it is changed to a spiral or circular mode. You need an antenna that can receive and transmit on both modes fairly rapidly to both hear the bird as well as transmit to it.
PS Before the ham guys jump me for being fuzzy or too simplistic, well lets just say that I tried to just phrase things to make them more understandable and in doing so sacrificed some detail clarity. And to tell ya they truth I have to look up half of this space communications stuff most of the time. |

WELL 833,
I may just have to recind my earlier post! Please put me on your "want to try one" list. I would be very interested in your antenna. Do you have any approximate dimensions yet? (I don't care about gain numbers - lol. If you've designed & built it I want one providing I have the room!) Ron |

I have built 2. One was left laying on the ground at the test range waiting to be picked up. The other is in my shop waiting to have the new improved mounting plate welded to it. I was out of the country and now I am trying to catch up.
The cat is not yet out of the bag, so keep it quiet. I don't think I was supposed to tell anyone that I was designing a new CB antenna. |
