    well,it def worked best on the ground pointed straight up lol..been up since 6pm yesterday. the astroplane has 2-3 s units higher than the quad with it up in the air on vert,the horz is not near as strong as it was when it was just a horz quad. the wqeight sucks opn my light weight design. let...

    taxes are done! back to the radio again..while on 27.505 i checked swr on am and they were 1.6- 1.7 vert and horz on the diawa meter. with all the diffrence between my radio swr meter and the cn-801 diawa meter i decided to change a 6ft old beefy rg8 jumper,,and swapped it for a cheap thin...

    hey Homer the fiberglass rods are three eighths thick, 3 foot long, with 4 to 6 inches inside the aluminum tube, my reflector and everything is built for channel 40, the reflector is 37 foot 7 inch the driven is 36 foot 8 inch the element spacing is 5 foot 4 inches, I have moved the spacing up...

    Now it is time to tweak it, you may experiment with moving the driven element a further distance away from the reflector, this will also change the impedance of the antenna at the feed point. this may be the simplest and easiest way of lowering your input impedance instead of experimenting with...

    its kinda a erie feeling having a swr more than 1.3 or so for me..but thats just what im used to in all the radios,mobile,and base ive had . i run a rci 2995dx 4 yrs old and have no clue what a high swr would tear up..but when im talking on this new vert and horz on ch 38lsb the swr never goes...

    1 wire dual polarized quad

    THANK YOU. i sure dont like all the extra weight on my spreader tips..and the beefy coax makes it hard to get closer to the feedpoint, the horz choke is closer than the crappy first try in the pic as i could get it comfortably.. i feel i will be steering away from this soon to be honest.because...

    1 wire dual polarized quad

    yes that one is,thak you. had a problem and fixed it with fresh solder on the horz center conductor where feedpoint was..both transformers are exact in length,re checked before wrapping other choke"NICE AND TIGHT I MIGHT ADD :-) on this one.. now with both chokes temp installed swr readings are...

    1 wire dual polarized quad

    incase this may help another antenna ignorant person someday; i just checked swr 10 minutes after last post and horz went down to 2.4 on ch 1 and 1.8 on ch 40??????????? i asked my ham neighbor how? he said the sheild was prob messed up or changed on that section..this seems true since that...

    wrapped the horz choke the same way for test purposes. swr is now def came down on vert since doing both chokes. with precise cut 75 ohm matching stub,for ch40 w/ 5 wrap choke ch1= 1.4 swr ch40=1.7 swr (its built for ch 40...

    ok just wrapped 5 turns around a 4 inch plastic piece..excuse my temp mud duck tape job. wind is bad today so needed it to stay temp only for now,does this look correct// swr were 3.0 before and 3.0--3.2 now with the choke wrapped out of my 75ohm transformer near the element.. ok wait..i DID...

    1 wire dual polarized quad

    so i ignore this ,that is still on my mind?? and why im cuntfused this says the 75 ohm air choke goes after my 90 inches of 75 ohm matching transformer??that would make the entire 75 ohm line 13ft 6 inches with the last 6ft a choke? you guys are saying use my existing 75 ohm matching section...

    1 wire dual polarized quad

    thanks for clearing that up fellas.. i have had the correct length 75 ohm from the beginning and from what i understood on page 1 i would add the 6 ft OF 75 ohm choke to the feedpoint end of my existing 7ft 6 inch long 75 OHM matching stub... so from what im getting now i will just cut off 2...

    from what im learning tonight reading the rg59u foam with the yellow plug is way better than the rg59 mentioned here by others..it has a lower attenuation at 1.5 instead of 2.0 and from what im reading here is why i mention this. http://www.qsl.net/g3yrc/coax.htm that yellow cable i thought was...

    1 wire dual polarized quad

    ok im still thinking ..i have to assume the rg11 im using is .84vf .so my tranformer sections are correct. so when i add the 5 and half "iirc" inch wrap of a 3-1/2 inch round coil of the rg59u at each feedpoint is this going to help lower my swr at all?? i will also appreciate help with the...
