    I wouldnt tune for fs unless your in bounceback and want highest forward gain setup
    dual hots are more omni directional i would aim for lowest reflect and be nice to your equipment also remember a high fs reading means the antenna is radiating well but at the same time it may not have a good swr in its resonant area so you have to find a happy place

    Yeap..im in bounce back .. i seem to have found the happy spot.. mfj has great readings and its very broad banded. My reflect with a 25w slug is about 10 watts at @ 2k bird. I was surprised that my mfj claims my resonant area is @ ch 24.. but the readings on the mfj barely change all the way up to 27.750.. (I didnt chk below freq's) i didnt even bother looking past there.. i stopped and chalked it up as good.

    hey D Max if your getting 10 bird reflect , part of your feedline coax is not right before the amplifier .

    i really think you had nothing wrong with the dual hotts before .

    alot of amplifiers are not tuned properly from the technician and therefore your reflect gets all messed up .

    the amount of coax you run after your radio is the most critical.

    If it matters the 10w goes down to 2-3w when modulation hits... The box tuning was checked last Sun.. on a bench.. deemed to be almost perfect.. by Dave.. I dont know why... it dead keys 10w reflect and swings down to the 2-3w which i thought was ok.. My output is forward swing and reflect downward swing. The FS jives with the output swing. i put a cheapo peak meter and its all fwd swing. I also find if i turn my drive wattage up.. the dead key 10 reflect will go to 5w and swing down... so im think im fine.

    well lets see. you bitched about my comment on how 2 hots was junk. you bitched here, face book, ratchet jaw......
    I even got a mesage from you about it....
    look where we are at now... I gave you my technical opinion, you did what you did, then did what I sugested and here we are.
    Dont worry I dont expect you to retract any of those comments.
