nice changes.

do you have a station a few miles away to tell if you are making a positive or negative difference in signal radiation?

i just did a couple of radio checks at 10 miles 8 foot of the groun and the 1 guy i usually talk to said i was 30s units and the other 10,i usually hit the first guy at 30 when my antenna base is at 40 feet so i am going to mount it and try again.i think the other guy i also usually hit at 10 but thats at 40 feet.gonna have to try it out its been down all week.

ok a confirmation from a guy in canada i talk to regularly that i hit at 3s units said i was 3.5 almost touching the 4 so 1/2 to almost 1 s unit increase with 21 feet 9 1/2 inches so far my receive is better gain about the same 1/2 to 1s unit my match after getting it back up went to 1.1 to my surprise across the intended band and further.i increased the loop gap to 4-5 inches and adjusted the tap point again.not done yet but had to give it a try before the next session!

cool!

im going to do the same sort of experiments when i get my maco, but that wont be for a while.

if you have a field strength meter handy, you can watch the real world signal increases and decreases your changes are making.

i cant wait to put up a real antenna again!
i have an inverted V up on the roof, but it leaves a lot to be desired. LOL

have fun!

cool beans i had this first one up after the imax snapped i think it worked better than the antron that was on the top of that same mast and the second one is up there now 33 foot loop in a different spot but once i get the maco finished i will use the mast as a hanger to my other roof with another hanger to hang this loop vertical.

how about midland 5/8 to .64.had this one laying around and decided to extend it to 23 feet match was 3.1 on channel 1.the neat part about this antenna is its extremely light about 3lbs.i still got some imax parts left too.

ok well i dont know about antenna theory however this midland is now 23 feet with out the matching coil and total antenna 23 1/2 feet i mounted 2 whips at the bottom and trimmed them down to 4 feet 2 inches each.my match is shocking workable 26-29 mhz and flat accross almost 2 bands.i used this last night with a trc-209 walkie talkie mounted about 7-8 feet with 3 watts out.2 stations one 10s units and the other 8-9 from about 10 miles.i will be mounting this about 25-30 feet tonight for additional testing and then pulling the maco back down.

on the ground those whips worked perfectly but when i got the antenna in the air the match went south! i ended up taking the whips back off and isolating the mast from the antenna bracket.the weird thing is i have a peice of fence post mounted to the back of my garage and i just drop the mast into it with a hose clamp to position it and that section of fence post with the mast was acting like a matching network.to match the antenna to the new .64 length all i had to do was drop the mast into the fence post and adjust for my dip!wow any comments would be appreciated!
