New Beam Causing Havoc

[Billygoat]

About 3 Days ago I Installed a New Maco 3 Element Beam. My Neighbor who lives 150 feet away Grab ahold of my ear yesterday and was very nice about the situation. She Explain that I was Interfering with every TV in the House, Her Telephone and Stereo. So Far I've Had a Imax 2000 On same tower and running 2k and never interfered. I Had a Maco 5/8 5000 On same tower Running 4k. Never Had a Problem. And Just took down My i10K pushing between 8 - 9K on same tower.. With no problems. Now If I run my same radio RCI 2995dx bearfoot... Is causing problems... All My Equipment is grounded in House and so is the tower...

What can I do??? any suggestions?

Make sure your radio is not overmodualating. also if you dont have a tvi filter, get one it will help.

[Red Warrior]

Did your SWR change between antennas? A bad connection will give those symptoms.

[Billygoat]

SWR'S Are 1 1:2 Across the 40. Also i'm using LMR 400... I Have the Tower grounded... Should I ground the Base of Antenna too? Also I was thinking of upgrading to RG217 Coax...

Thanks for the Help

You need to wind a coaxial rf choke and have it at the base of the antenna. This will eliminate the coax from radiating . Always at the base of the antenna so no coax
Basically a rf choke is 7-8 equal turns of coax approx 6 inches across in diamater. use tie straps or good black tape to hold it in place Coffee cans make perfect size molds.Slide the coax carefully off the can and please dont leave the can up in the air with coax taped to it :D .

I guess if that doesnt work you can always not point the antenna in her direction but to me thats not an alternative. I like solving the problems.

I have a 2995 that is SWPed, but no other power, an Imax 55' up on a tower, ground rod at the base, and ground strap. I do not run the 2995 wide open, DK about 90, swing to about 200. I bleed the surround sound system in my own house, now if I turn the mic gain up past about 1 oclock my friend down the street calls me to tell me I am bleeding his surround system, I turn it down slightly no problems. I have tried grabbing the coax while transmitting and don't see any difference, I believe it is the modulation level in my case.

Don't think a coax upgrade will make a difference. Let's see....you had all those vertical antennas, running high power and no problems. I'll be willing to bet you installed the beam horizontally...then the problems began. If so there is some horizontal component in her house/area (wiring, gutters, fence, etc.) gathering your rf and easily transferring to the appliances. Try the thing vertical and see if it stops.
On a side note RCA engineers Gain and Greyline proved without a doubt that modulation qualities of certain speech components are more effective on horizontal antennas.

I agree, I'd try a coaxial choke balun at the boom, reasonably close to the gamma match.

[Billygoat]

As of So Far. Maco 3 element is vertical, Changed gamma To 100K, Installed New 218 Coax. Did the RF Choke. Ground Rods are in Place. I Run A Shure KSM 44 studio Mic into a Tube Pre-amp T1952 and then into a Processor Then into My RCI 2995dx Into a Fatboy Straight 6 Into A 3XC10000A Tube Box. And Still Causes Problems... If My beam Is faced away from everything.. it only puts lines in her tv but can still hear me talking. and the antenna is about 20 Ft above her roof line. Also I purchased Rfi Filters and they are installed on here tv's. I'm just going to by a 500ft roll of 218 and move tower to back part of property... I really don't ever face the beam east so it never be pointed towards the houses....

Thanks

This beam is a directional antenna. You have it mounted on a rotor?
You can experiment with aiming rotor at different directions to see what causes the most trouble.
Is this mounted vertical or horizontal?

Toss my theory out the window
Sorry

The second 2995 problem...........

If you have had ANYTHING.....CUT>>>CLIPPED>>>>REMOVED........or ect..........this causes tvi......find out about your transmitter

The antenna........DOES NOT cause tvi.....IT may radiate the signal differently....But the trash on the signal was there to begin with...

a transmitter can obtain 100% performance without all this.......

Any update?? Were you able to stop the RFI and TVI to your neighbor?

[fortymobile]

One question do you have Guidewires ?????
