    Another vote for "do it"

    For a number of years I ran a Kenwood 2m all-mode for CW & SSB into a Mirage 160w amp into an M2 11-element beam at 45 feet. The amp very often made the difference between making the contact and not making the contact.

    It certainly helps.

    Even more than getting two tens for a five.

    first 100 watts is the most important, especially from 25 watts.

    There is no replacement for displacement.

    Yeah, it's a dB thing.:)

    25W -> 100W: 6 dB
    100W -> 160W: 2 dB

    The extra 2 dB is worth it when you're trying to work a signal that's 1 dB over the noise.:p But the 6 dB really helps.

    Those who are really seriously into VHF work often spend serious $ for a 0.5 dB improvement. Back in the 70s-80s, I was guilty of that, myself. I'd spend $200+ and several hours of work to replace my 1/2" hardline with 7/8" hardline on 2 meters, and the resultant benefit was literally about 1/2 dB on TX and 1/2 dB on RX, so total station improvement 1 dB. But I was a bit nuts, and so are a lot of weak-signal VHF-UHFers.

    HF can spoil us. I can lay 50' of hookup wire on the ground here and tune across 40 meters and hear 100 signals just fine. More like a thousand if there's a contest.:p

    At VHF height is King! I'd go up to Mt Equinox at 3800 ft and work stuff with 10 watts that nobody else could work unless they were on a similar location, like Mount Greylock to the South. Yes, we could easily see each other's mountains! But, it took some technical skill to bring a station that wouldn't be clobbered by the 150 transmitters at the summit. I had a booming signal if I ran an amp. What made it special was that I was so much higher than the surrounding terrain.

    Going fast is easy.
    Turning and stopping is the hard part.

    Going from 25 Watts (but isn't the TS-711 only 10 watts???) to 100 Watts IS a decent increase; going the extra power to 160 Watts may or may or may not be helpful. The REAL improvement (in your radio and/or antenna) is if you can hear them, but they can't hear you. If you can't reasonably hear them, increasing YOUR power just causes more QRM.
