Fob: I'm not sure I understand your point. You asked for the SWR measurement and I provided it. Of course I measured the SWR with a meter.
If you're trying to say that SWR does not provide a measurement of antenna pattern, you're right. It is quite possible to have a highly distorted antenna pattern with an SWR near 1, a directional antenna is deliberately designed to be so. SWR is at best an indirect measurement of impedance matching and is primarily of interest to insure that the voltage at the drivers does not exceed their breakdown voltage. Most comm radios have a max SWR limit (usually about 3:1), which is why we're required to measure the SWR at the radio during installation.
I haven't measured my antenna pattern, although I haven't noticed any operational problems. I've talked to an RCO about 80 miles distant. Measuring the pattern has been on of those things I've been meaning to get around to, but haven't done it.
I'm not saying that mounting the antenna on the wing is wrong - most Cubs have them there and work just fine. I'm just pointing out that an imbedded dipole is a viable option, for those who don't want the antenna on the wing for any number of reasons. Personally, I like the clean look, and a previous installation on the fuel tank cover cracked the cover (over thousands of hours - the plane was used as a trainer.)
