Swr question

[Backwoodsman]

Here is a goofy question.....i moved.....need to put my 102"as whip up as high as possible for my base....ok ....no problem.....runnin some copper as a ground plane.......i have a perfect 1 swr on 3 meters plus the radios meter (this is the mobile)with the 102ss. I put on a new in the box wilson 2000 trucker.....cannot get see below 3. Put a fiberglass 3' 4' and 5'.....3.45swr......i tried many locations on the pickup.....All get a 1 with 102"sswhip......3 0r more with even a wilson 2000 or the 5000....same coax even!....whats going on here? .

theres no better antenna for mobile use than the 102" whip. Anything else is just a compromise. the ones you mentioned will only perform at their best in one spot, on top of the roof, but even then its not going to match the whips performance. if you already have a whip then why you messin with the other junk

[Backwoodsman]

The reason for the other junk is I want to set up my base and all I have is the 102" ss and all my 'other'antanas and different ways of mounting them......i guess I can leave the 102" on the truck and build (or buy)a wire dipole....saw one for arround 30$(was a double bazooka I think)those are my only options to have a base and a mobile........i really hate to be without a mobile and miss a base....

And i just found a 102"ss whio for rhe same price as the dipole! Ok....got it figured out and when I can get this base set up we will see what happens.....thankyou for the input....427 is backin down..

yeah you could go with the wire, but I never thought they did as good once you switched to the horizontal orientation of the wire dipole. I stiil say the whip is best and the fact you want to stick it on the roof of the house doesn't change my thinking one bit. it should work up there just as well as it does on a truck. if your concerned with the ground plane, do like my old man taught me. cut a length of 10 gauage stranded wire about 102"long bolt it to the ground side of the mount and let it hang straight down. don't worry about radials try that

[Backwoodsman]

Copy that buztanut......will do......thanks for the input .......427..wavin at ya ....standing by

[d_bro2001]

that's actually a pretty good set up. the trick would be to get it as high as possible above the roof line. meaning of course, cutting a 102" metal pole and attach your mount to the top of the pole maybe a chimney strap to hold up the pole. with it like that you can forget about the hanging wire. you'll have good wind load against those supercells and you can load some watts on that whip too

[Backwoodsman]

Not a bad idea........sort of a vertical dipole.....still gotta ground the setup after I decide on what/how to build this......say....would that then be somewhat directional?

[d_bro2001]

no its still going to be Omni. as far as grounding the whole set up, do ground the rig and amplifier(if used) but as far as the antenna goes, remember this designed to be mobile so everything south of the mount its looking for a car body or as suggested a 102" length of wire. anything else you do south of the mount is viewed as the ground plane so a long wire to attach to a ground rod will be just that 102" on top and 50 ft on bottom. mismatch, 20 ft pole isolate the mount from pole contact and use 102" wire or in the unlikely scenario of a 102" pole not isolated, but securely mounted and at a height that's good (chimney mount) the wire is better because you can easily trim to tune if its lightning your concerned with then were going to have a long egghead theory session pop some corn

That's why I was thinking the whip and the 108"copper wire at a 45 degree angle....i haven't bought a second whip as of yet but I do have a francis that is 7' or so long I bought 20 years ago and never used...it has a perfect 1.0:1 swr where ever it is mounted on my truck. The radio shop that sold me it said that it has a resistor in the base to keep swr perfect.....and it has 2 wires running its length to produce a 2 decibel gain.....i might use that as I do not want it on my truck...seems the ss whip is more durable.......i might try this as soon as I get a power supply for the galaxy
