How to Stack two Triband Yagis WB5EMX on 22/7/21
Apparently this is done more frequently in Europe than in the U.S. Using two yagis in parallel tends to reduce QSB.

I have decided to build up some IF strips. I've never done this. I would like to see a discussion r.e. choice of transistor (what, aside from Ft determines a good candidate?), and I would like some recommendations of various types (i.e., some BJTs, some mosfets, or other types) so I can look up their specs, and maybe buy some.
Oh, and if there are other comments r.e. IF Amps, I'm interested. Also feel free to PM me at WB5EMX@ARRL.net
Thanks, Bob, WB5EMX

Incredible response, VT. Answered my question with surgical accuracy. I'll dig around in the Antenna Book, do a bit of self educating.

I have a couple of Triband Yagis for 10, 15, and 20 meters. I'd like to stack them. Is this when one should use a Wilkerson Power Divider? How far apart should they be placed? Suppose I purchase the kit to run one on 30 meters. Can I run them paired up except for 30? Has anybody done this before? What kind of spacing was used, and what technique was used to harness them? Thanks. Bob, WB5EMX

I recently purchased an old Explorer Tri-Band Yagi. Now I'm sure there have been so many folks traveling down the "Refurbishing My Yagi" road that you must have a Link to share for this project.

I also have two other damaged/parts missing Tri-Band Yagis out in the shed. AT this point in my life, I may never get any of them up 70', but I am pretty sure I can hit 30' maybe 45' for a pair of them. Running a full QRP Gallon in a QSO Party might just be a good time!
