Back a Few Years Ago I Bought Some Aluminum pipes & Antenna Parts From a Hamfest, I Think It Was The Peaton Ham Fest.

Shortly After, I Built This 9 Element Monster From a QST Article, I Never Had The Time To Put It Up And Install It.

About 5 Years Ago I Moved To this QTH, Put Up One 30 Foot Tower But Could Not Install Any Antennas On It Because I Found Out That I No Longer Could Climb Towers As I Use To In My Younger Day’s.

It Was Winter And Cold And I needed To Get On 2 Meters., But The Only repeater That I Can Hit Was KA9QJG 2 Meter Repeater.

I needed To Put The Antenna Which Was At 5 Feet Up On The Tower, So I Called On a Good Friend Bill KC9MDS AKA DR. Bill.

He Came That Winter 5 Years Ago And Installed The 2 Meter/ 70 CM Dual Band Antenna On The Top Of The Tower, We Tried To Put Up My 6 Meter Yagi But It Was So Cold I Thought That DR. Bill was Gonna Be So Stiff From The Cold Temps That He Will Get Stuck On My Tower And I Was Not Having That (LOL) So We Called It Off.

This Moth I Was Thinking That It Is a Shame For Me To Have a Tower And Not Have Yagi’s On It, So I Called On My Fiend DR. Bill, We Talked About Putting Up 3 Yagi’s Up On The Tower, One For 2 Meters One For 6 Meters And an HF Tribander.

On Saturday The 16th Of October 2021 Bill Came And Installed The 2 Meter And the 6 Meter Yagi’s, There Was No Room To Put Up The HF Tribander.

About 3 PM DR. Bill Was Tired So We Halted Work Till Next Monday Installing The Rotator And Tyding Up The Cables ETC.

I Needed To Test The Antennas So I Called My Other Good Friend DON KA9QJG, The Antennas On Both Bands Performed As Expected.

Later On, I Heard DR. Bill & DON Talking About The Antennas, DR. Bill Was Asking If I Designed The 2 Meter Yagi On The MMANA Antenna Modelling Software…..  I Told Him That I Did About 4 Or Five Years Ago Getting The Plan From That QST Magazine Article But Promised Him That I Will Do The Design Again Today And Make a Post On It, So Here Is The Software Version Of The 9 Element 2 Meter Yagi, I Hope This Could Encourage New Hams To Start Building Their Own Antennas.
