ok my responces go back and forth between base and mobile antennas and after reading what I stated i sound like a flake to myself. thing is, duals give you both sides stronger and if off set on the mobile, front to rear , compared to a center mounted antenna. you dont lose the (my ex was rear...
I dont have a problem with what was stated on that page, now take those same duals that they had centered and move them forward or backward on the vechile off center and they become directional. but because as the picture showed you dont lose side to side. an as i stated duals combined output...
In my day we called co phase making duals talk eveninly and maling them directional was refered to as fixed phased. Doc Id like to chat with you sometime, your very sharp. My Dad and I actually used fixed phased CLR 2s back in the early 70s. then he put up a long john 5 element.. beams do as you...
thank you but havent you every had or know anybody that run dual beams? effefancy losses to ground arent as bad on mobiles becuase of the entire vec being grounded .if you think im wrong bout the duals antenna being equal to a single. point to me where it is . ive seen and used ARRL hand books...
I agree with you that phase timing is a great way of making 2 omni directioal antennas directional. but because of space on mobiles it isnt usualy done, my point with the dual antennas on a mobile is you use the autos body to direct your direction of talk. i stated that 1 centered high on the...
world population has encreased and so has the availabilty of radios all across the world. and so has the jerks population encreased and the old timers use big power and are still curtious. just got to over look the other people,for lack of a better word. thanks
I happen to be 1 of those rednecks from back then, actualy before then from 60s really. and I agree those so called CBers are really a pain, glad we lost alot of them. maybe the Lord will bless us and the jerks today will burn up their trash radios
Belden has been making coax for over 40 yrs that I can rember and they invented the 'mini8' and unless your using a large amp. loss on the small coax is miniscule at best. if i sound uphanded please to read this that way. I only like to share what Ive learned growning up round bussiness band and...
the lil wil is a mag mount loses a slight bit on ground,as opposed to the 1000. and the lil wil is a 1/4 wave while the 1000 is a 5/8 wave. So I agree with Mr Clean.
A second idea. dbl check your swr s on 40 and one see if one is slightly higher or lower than the other. if higher on 40 whip is to long and adding springs wouldnt have helped. been yrs since i bought a 102 whip. use to be they were a little short, but might have changed over the yrs
make sure the plastic insert on the mount (if like the ones pictured here) is on the antenna side. if not itll be a short, not likly though, swr seems low for that. try putting a 8' piece of rubber hose on the bottom of the whip ,on the chance that the bar and lights are all grounded right. the...
Antennas: single antennas are great, if your mounting them in the center of a roof , on center of trunk right behind the rear glass;base loads are best.theyll talk ground wave, they talk skip.Old school"bigMommas" new "Wilsons" are both good. A figerglass whip about 4' like the...
to answer the guys question bout the pic he actually did get posted. could be a moonraker or maco four element. longjohn . several companies made no-cross fired beams.:)
the Imax without the GPK will give about a 1/2 s unit higher signal than the A99 with the GPK but add the GPK to the Imax and then the Imax wins hands down. Imax GPK is worth alot towards the horizen. thats ground wave :)
if the Imax is put about 9' above the beam unless both are powered together the Imax will be invisible to the beam, the reason is theres nothing for the beam to reflect off of, power into both at the same time causes the rf fields to intermesh and sque, but one with remain invisible to the...
you ll find that about a 1.5 inch space between the middle sections of the dipole and 72 ohm( rgu59) coax instead of 52 ohm RGU8 will help bring the swr down, alls left is fine tuning the lengths ;)
dual antennas are directional to the longest ground plane direction, but; the right side talks as far left as a middle mount. as the left viseversa. both talk the short front or back equal to the middle mount because they dble . and as already sated above the longest ground pklane they are...
