Title: Yagi Antenna
Post by: mike-km4btw on April 12, 2018, 08:52:39 AM
Which do you think is better, directly fed with bonded elements or insulated elements? Gamma match or directly fed?
Food for thought. Comments?

I have made more than 20 yagi antennas for 2 meters and 1 for 6 meters and found that the gamma match was the easiest to tune and construct. I still have 8 aluminum and stainless gamma matchs left over from classes antenna construction class I had about 15 yrs ago.  The grounded metal elements were the simplest to make.
I used u channel aluminium stock and 1" square fiberglass stock for 3 of them.
