    I think the OP's question has been answered: bad idea to lay flat, SWR will most likely change some, how much ?????

    At no time was a SCR-522 refured to as UHF..

    ( http://www.rigpix.com/military/scr522.htm ) .... And the PL-259 did not exsist in 1930 ...O by the way At one time 400 mhz was caled QUASI-LIGHT waves By ww2 the current bands exsisted as is

    To get a tube to work at 5 meters you had to take the base off ....

    While we are at it it was beleved that frequencies above 28 were open to anyone because they were useless ....

    Yep, question answered thanks to all. I did raise it back to 90degrees, swr changed very little and to be honest I cant tell any difference on recieve. Although the transmit could be better.

    Windsmith,
    I to am a former broadcast radio engineer and I tip my hat to you for the excellent and easily understood tutorial on standing wave ratios and the influences thereof. How about smith charts next time or do ya think you'll loose your readers?
