[RFI] Subject: Re: Recommended Handheld VHF-UHF Yagi?

[qrv at kd4e.com]

OK, good point.

Is there any advantage to a simple yagi, quagi, quad, delta loop, or
circular element beam - or will all perform about the same?

Each form factor has an impact on convenience; e.g. weight, ease of
maneuverability, broadbandedness, matching system, etc.
