why does it seem like 90 percent of the threads end up pluging the i-10k?how about a imax 2000 with 102 inch whip on top and grounplanes at 30 degrees!if i wanted to spend 400 dollars on an antenna i would by a beam!

i believe the broadbandness is due to the matching coil not the #14 wire. and think you are right and a thicker gauge wire may be more broadbanded.the radiator length however does not fall short of a 5/8 wave but at least a 5/8 wave to a .64 wave at 22 1/2 feet.if you try different calculators...

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...

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...

this was the imax this spring after the old rat shack mast snapped where the section insert into one another.ouch poor imax!

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.

hey remember that thing is horizontal if you want to here in another direction turn it perpendicular to where it is if it was on a rotor or a movable pole you could move it,you are probably transmitting off the two sides of your garage.i had one horizontal and it tore my antron up in two...

i sold my avanti 101 about 10 years for 25$ wish i still had it.that sirio is what i believe to be the third version of that astroplane.my original av-101 was 12 feet tall and not to long ago they were listing the old style astroplane extended to 18 feet(i would love to try that one)and now this...

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...

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...

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...

you really dont need one if you were having swr problems than that might help.good deal enjoy!

loose cannon i am getting closer and got more pics.so far i have a length of either 21-1/2 inch radiator or 21-9 1/2 inches entire length with the dip at 32 and 1.15 and 38 at 1.2 and 55 at 1.3 maco states to measure the full length from top to bottom.the loop gap is still at 3 inches maco calls...

cdx i am trying to get as much length out of this antenna without changing the design so far so good i have managed to get the length over 21 feet and the match to 1.2 on 38 and 1.3 on 55.i have made minor changes so far by dropping the ground planes down to the mounting bracket and increasing...

ok thanks for your help doc.i spreaded my loop out a little and my match came down on all bands!i think i need a bigger loop.

good call loose cannon heres mine match was 1.1.

insulator.update i took the extra small radiator out of the antenna and managed to get the regular antenna to stretch out to the same 22-10 inches results are 27.555-1.3,27.385-1.3,dip in the middle but still not broadbanded still working on it!PS-w5lz thanks for all your help,i hope i am not...

ok sorry here is the insulator at the top.question for you?according to a frequency wave calculator for 5/8 wave length on 27.485 comes out to 22.375 after that # i multiplied it by .015 to make up the difference=.335 then i added it to 22.375=22.710 now i have heard that antennas tend to be 5%...

sigma 5/8-maco 5/8. note the groundplanes are suppose to be 1/2 from loop bracket not the case here.

no ground wire hooked to mast-mast in the ground.
