Under 3 without my antennas upright and under 1.3 upright.

1.2 here too, tut id say average is more in the 1.5-2 range. You're doing well with the 1.2 :D

1.1 - 1.4 depending on the channel. Most people I wheel with use channel 4 so that's the one I tuned to 1.1. Channel 40 is a long way from there so that's why I get a 1.4.

Tech Question: I have tunable Firestik antenna. Tuned it down to 1.2... happy. Put the cap over the adjusting screws and the SWR spikes. I ended up readjusting, replacing the cap each time, to get a final 1.2 with the cap in place.

I never thought the rubber cap over the tip could impact the SWR to such an extent. Last time, I didn't check with the cap after obtaining 1.2. Are you reading your SWR with the cap reinstalled?

Common Causes of High SWR
Compliments of Firestik® Antenna Company Technical Support Team

Copyright © 2007 Firestik® Antenna Company

There are many things other than the antenna that can cause high SWR. SWR meter readings take into consideration the antenna, the coaxial cable, the mount, the mounting location, the vehicle and objects in the antennas near-field environment. We broke our list of common high SWR causes into six primary categories. The order of the categories does not imply that one is more common than the other, however, the list within each category is arranged based upon our experience and shows the most common causes higher on the list than the lesser common causes. Get to know the basics of SWR by reading the article "What is SWR?".

ANTENNA RELATED

Antenna was not tuned in its final mounting location
Antenna tip installed AFTER the antenna was tuned
Testing or tuning with doors, hood or trunk open (altered ground plane)
Antenna not mounted vertically
Incompatibility between antenna and vehicle for undetermined reasons
Insufficient tuning range due to antenna/installation incompatibility
Antenna tested/tuned inside garage, carport, etc.
Antenna was tuned then moved to another mounting location or vehicle>
Ground plane and no-ground plane antennas used with wrong coax cable type
Antenna grounded to vehicle chassis ground circuit
Internal antenna issue (verify base to tip continuity)
Antenna not designed for use with CB radio

ANTENNA MOUNT

Ungrounded mount (re: ground plane dependent antenna system only)
Relying on a chassis ground via the radio (must test with coax off of radio)
Anodized or powder coated mounts (insulated from chassis ground)
Antenna stud mount improperly installed (shorted)
Coax shield side not grounding to mount (re: ground plane dependent antenna system only)
Improper positioning of required insulators on antenna stud

COAXIAL CABLE

Open (broken) center conductor or shield
Center conductor to shield short (undesirable connection)
Severe pinches, sharp bends, and/or cuts in outer jacket of coax
Excess coax rolled into a coil for stowing.
Low quality coax cable
Antenna/Counterpoise anomolies and potential coax cable resonance
Wrong type of coax (Use ONLY 50-ohm for single antennas, 75-ohm for duals)
Using a standard antenna with a no-ground-plane cable assembly or vice versa

MOUNTING LOCATION

Antenna running parallel to reflective surface over too much of its length (and too close)
Antenna mount affixed to an ungrounded in-bed pickup toolbox
Antenna mount affixed to insulated roof rack (anodized or powder coated)
Antenna mount affixed to an ungrounded spare tire swing arm
Antenna mounted too close to other antennas (24" minimum recommended)
Less than 60% of a top loaded antenna in free air-space
Dual antennas not having unobstructed line-of-sight between top 60% of length

GROUND PLANE (COUNTERPOISE)

Vehicle is a composite material (fiberglass) - NGP system required.
Insufficient ground plane size (motorcycles, ATV's, etc)
Running too long of a wire from mount to chassis to ground the mount
Thin sheet aluminum vehicle shell (insufficient metal mass)
Antenna positioned in a manner that doesn't allow it to use available metal counterpoise

SWR METER

"To Transmitter" and "To Antenna" coax leads reversed
Failure to recalibrate SWR meter after every channel change
Calibrating meter when in SWR/Ref mode instead of Cal/Fwd mode
Innaccurate, defective or uncalibrated SWR meter
Unable to calibrate meter to set line (radio output power issue)
Improper testing procedure
Faulty coaxial jumper between radio and SWR meter

CB RADIO

Defective/damaged transceiver (radio)
Insufficient current to transmitter is limiting output
High resistance 12v power connection
Partially broken wire on either positive or negative 12v lead
Loose connection on either positive of negative 12v lead
Corroded power lead on either positive or negative 12v wire

Mine doesn't move the meter to 1.1:1 toward the CB channel ends but I did it just to see if I could (revisiting my Ham days) - combination of ground to frame, coax cut to length, and antenna trim.

1.2:1 is really good - don't mess with it!

I have to recheck mine.. Forgot about it being on there and whacked the crap out of it in a parking garage.. :shaking::pissed:

Maverick, How dose tuning the antenna with the doors on and then taking the doors off relate? Will this screw things up? I tuned my antenna in the early fall w/doors on and reinstalled rubber cap after every time I adjusted the antenna. I also fallowed the instructions from the meter and the antenna to a T(I am very anal when it comes to my Jeep).

p.s. I have a 3' Firestick mounted on a fabed stainless steel mount on the tailgate.

Sorry. I am by no means an expert. I simply made the observation tuning my CB and recently found clarification on Firestik's website. I understand you should tune your CB reflecting the conditions you intend to wheel... doors on/off and away from structures (shop, house, etc.). I would think the hood and frame serves more as the antenna and not the doors. I suggest doing a simple test. Perform a baseline with your doors on and then take them off and compare. Please share your results! :D I have a 4FT mounted on my KC windshield mount on top of a quick disconnect so I "don't bang it in the parking garage" upon the ocassion I drive it to work.
