I've compared a fully extended Miracle Whip with and without a shorting lead between whip and coax centre connector (i.e. with the Miracle Whip circuitry either out of or in circuit). On an FT-817, there was significant improvement in signal strength when the short was removed and the antenna peaked for the frequency in use. The improvement was substantial, typically 8 or 9 S-points! The same level of improvement was seen using the VR-500 instead of the FT-817, making make barely readable signals fully copiable. Having said that, a fully extended miracle whip is rather unwieldy on a VR-500. Much better would be an equivalent length of wire and the Miracle Ducker or similar.
