BBTD Antenna


Chuck Ferguson - N4CSF
 

All,

Please see below -- for your information -- an interesting article written by Darrell Franchuk KG4CCB in Reddick, FL, who is building a new house in Tellico Village and hopes to move here permanently in the Jul/Aug 2023 timeframe.  He reached out to me previously and thought this topic might be of interest to some of our members.

His article deals with the design, installation, and operation of a Broadband Butterfly Terminated Dipole (BBTD) antenna for attic or exterior roof applications.  He notes prior TLARC discussions about this design and considers it to be a rather favorable antenna option, especially when Homeowner Association rules prove overly restrictive for directional outdoor installations.

Please read the article, and decide for yourself.  I've included Darrell's e-mail address in the Cc: line.  So please contact him with any questions, comments, and/or welcoming words of encouragement.  I think Darrell would be a wonderful addition to the TLARC family!

73,
Chuck N4CSF

Chuck,

While working on a article for my local club newsletter about a BBTD Antenna I came across an online link to a TLARC Groups page with a discussion about TLARC activity with such an antenna in early 2019.  That discussion was 'theoretical' in nature and question the antenna radiation efficiency.  My article is practically oriented and I thought it might be of interest to some in TLARC.

PS:  We expect to be moved up there in July or August.

I’m not antenna expert by any stretch.  However, I have an X50 in our attic in Toqua that hits many of the area repeaters between Kingston, Madisonville, Maryville, Oak Ridge, and Knoxville.  If you mount your’s outside, I’d guess you’ll have no issues hitting the Knoxville antennas and beyond.

Thanks.  The ID I indicated below is from TLARC website.  I'll try again later.

I was interested in learning about repeater access.  Our house on Kawga Way in Chota is currently underway (roof just finished) and I am prepping for antennas.  I will put a Diamond X50 2m/440 vertical on a 20ft mast (easy access to TLARC repeater), but was wondering if that will enable me to hit Knoxville repeaters, or if I will need to put a 5 or 7-element Yagi in the attic.  Comments?
