Quick and Dirty Antenna With Good Performance (especially way out west)
I have an MFJ-1024 on top of a 20' pole that works very well. It
behaves exactly like a car radio antenna (which the element actually is). I use it on my little bed side radio (an ICOM R-75) and use it nightly. Caution: when buying antennas from MFJ or Radio Shack, I find the first thing you need to do is take them apart and tighten everything. The Stoner DA100E is pretty much the same thing, but they may be on hiatus. |

Small Vertical {Omni} Active Shortwave Receiving Antenna and Free-Standing "Grounded" Metal Mast {Top-Rail} Mounting
Greetings RHF& All!
I appreciate the posts and ideas here. I have a 102" whip out in my building that I have been trying to figure out what to do with it. I can't afford the MFJ-1024 or anything like it. I have the Radio Shack amplified indoor active antenna. Would it be worth my while to place the 102" whip on top of the rail as you suggest and use the ground and run my coax into the Radio Shack indoor amplified antenna? Would this perform any better than say a long wire antenna or a loop connected to my active antenna indoors? I can see that the active antennas you linked to were of much better quality and features than the RS antenna. Tell me what you think. Thanks ahead of time! Jon in South Carolina. |

MK - So 'you' now Claim that 'you' Get Off . . .
Having Someone Hump 'your' Legs / / / / / Sorry the Topic Here is "Shortwave Radio" and the "Alt.Sex.Get_Off.Leg_Humping" Group has a completely different URL and Charter. My Subject was : Small Vertical {Omni} Active Shortwave Receiving Antenna and Free-Standing "Grounded" Metal Mast {Top-Rail} Mounting - - - May not thrill you but it may provide 'the answer' to a Shortwave Listener (SWL) who only has a small lot or neighborhood restrictions that limit his Shortwave Listening (SWL) Antenna Opinions. The SWL is considering a small Vertical Active Antenna as their primary Shortwave Listening Antenna. - - - The SWL's Question - How Do I Mount It ? What was posted was one option on How-To-Mount a small Vertical Active Antenna for Shortwave Listening. MK - Check-Out - REC.RADIO.AMATEUR.ANTENNA If you are really interested in Amateur Radio {Ham} Antennas then the "Rec.Radio.Amateur.Antenna" NewsGroup may be a better Forum to express your views and their Focus is Amateur Radio Antennas and believe me they do get very Knowledgeable and Technical in their posting. http://groups.google.com/group/rec.r...mateur.antenna mk - it's has been nice hamming it up with 'you' ~ RHF |

Two comkpanies offer active antenna kits worthy of 'sperimentin with. Each is in the $10 range: Ramsey and tentec Yodar |

Greetings Yodar! I forgot to mention that I also have the Ten Tec
active antenna and for me it does not work quite as well as the Radio Shack version. I have seen the Ramsey kit online but have not really studied it. Part of what I am wondering about is what are the advantages of having an outdoor active antenna verses an indoor active antenna. Thanks for the suggestion! Have a great week!

JON,
READ - Two Do-It-Yourself "Kits" for Ten-Tec : RF Pre-Amplifier and Active Antenna http://groups.google.com/group/rec.r...8c5523e79b8e0a http://groups.yahoo.com/group/Shortw...a/message/5920 Take your TenTec Active Antenna and mount it on the Free-Standing "Grounded" Metal Mast {Top-Rail} as described in the prior post. Use a CB (10m) Whip Antenna for the Antenna Element. Ensure that you have a Ground Rod built into the Concrete Anchor of the Top-Rail and that the Mast is Grounded. Place a Snap-On Ferrite Core (Bead) within an Inch or two of both {each} Ends of the Coax Cable Feed-in-Line between the Actve Antenna and the Radio. FWIW - Using the Free-Standing "Grounded" Metal Mast {Top-Rail} is a good idea for 'mounting' small Vertical Antennas. 1 - Elevates the Antenna away from the RFI/EMF envelope of your House. 2 - Grounds the Active Antenna Module and Coax Cable Feed-in-Line. 3 - Run the Coax Cable along the ground; or better yet Bury the Coax Cable under-the-ground as much as possible. TIP - Ensure that the Free-Standing "Grounded" Metal Mast {Top-Rail} is located at least 20 Feet from the House and other structures to also get it away from the RFI/EMF envelope of your House. DISTANCE AWAY - Out-and-Away and Up-and-Away are both Important to Reducing the 'relative' Noise that your small Vertical Active Antenna must exist in to pick-up and receive signals. Placing the Antenna Element Out-Side the House's RFI/EMF Envelope {Physical Distance} is one of the simplist and most effective techniques in creating any Low Noise Antenna. IMHO - You should here a lot less noise and better quality signals with this Out-Side small Vertical Active Antenna set-up then with the RadioShack {InDoor} Active Antenna. hope this helps - iane ~ RHF |
