What is a butternut antenna?
Butternut (formerly part of Bencher, now belonging to DX-Engineering) manufactures HF antennas since 1981. The multiband verticals work very efficiently, also on the low bands. Due to it’s robust construction and simple setup, the HF-6V and HF-9BV are among the most popular all-purpose antennas for DX-peditions.
Who makes Butternut antennas?
DX Engineering
Butternut antennas are now made by DX Engineering, continuing a decades-long tradition of setting new standards for quality Amateur Radio vertical antennas! Butternut’s trio of critically-acclaimed vertical antenna designs, including 2-band, 6-band, and 9-band models, provide excellent HF performance.
How do I lower the SWR on my vertical antenna?
If your antenna is mounted down low on the vehicle, like on the bumper or behind a pickup truck’s cab, the signal can bounce back to the antenna, causing a high SWR. To alleviate this, keep at least the top 12 inches of the antenna above the roof line, and position the antenna as high as possible on the vehicle.
What happens if SWR is too high?
If the SWR is too high, not only is the performance of your CB seriously hindered, but you run a very high risk of damaging your radio. You need to make sure that there isn’t too much power being reflected back into the radio through the feedline from the antenna, which prevents the proper signal output.
Should my CB be set on SWR or S RF?
The CAL and SWR positions are only for checking the SWR of the antenna. Recommended Setting: The S/RF position. SWR – This is a measure of antenna performance. It tells you how well the antenna system is tuned to the CB band.
How do I bring a SWR down?
Is 1.7 SWR good?
SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape.
What SWR is too high?
If the SWR on channel 40 is higher than that on channel 1, your antenna is too long. If the SWR on channel 1 is higher than that on channel 40, your antenna is too short.
What is an acceptable SWR reading?
SWR Range Explanations. SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. If you’re at 1.5 and really, really want to drop down to closer to 1 it’s likely possible to do with addition tuning, different equipment or a different mounting location.
Can CB SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less.
Is a SWR of 1.5 ok?
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
How do you get high SWR down?
Can a pinched coax cause high SWR?
Damaged coaxial cable is a big reason behind high SWR readings. A coax can get twisted, shorted, or pinched while routing through the vehicle.
Is it OK to coil coaxial cable?
There’s nothing inherently wrong with “looping up” extra coaxial cable. In fact, a neatly wound coil of coax can function as an air-core choke balun (“ugly balun”) which is useful for some antenna systems when located at the feed point of the antenna.
How do I lower the SWR on my antenna?
Does ground plane affect SWR?
An inappropriate ground plane is one of the major causes of high SWR readings. You should select a sound ground plane with an entire metal surface. It would be best to run the ground straps to as many parts of the vehicle’s chassis as possible. Keep the straps as short as possible.
Does cable length affect antenna reception?
Yes, the greater the length of coax cable you use, the more signal loss you will experience.
How high is too high SWR?
3.0
You SHOULD NOT transmit with your CB at SWR levels above 3.0. If your SWR needle swings all the way to the right (off the charts) when getting your 3.0+ readings, you almost certainly have a major installation problem.
What is the best ground plane CB antenna?

What is the farthest a TV antenna can reach?
Commercial Over-the-Air TV antennas are marketed with distance ratings between 20 to 60 miles (for most indoor models) and up to 150+ miles (for ‘extreme’ outdoor models). But, in real-world conditions the idea reception areas for antenna TV are within about 35 miles of local broadcast towers.
How do I increase coaxial signal strength?
Install a house amp. Amps are devices used to boost a coaxial cable signal; they can be purchased at most electronic stores and installed per the manufacturer’s instructions. Your cable provider can often send a technician to your home to have the amp properly installed.
How big does a ground plane need to be for a CB antenna?
Does a 1/4 wave antenna need a ground plane? Answer: Yes. All 1/4 wave antennas work best if they are installed in the center of a metal ground plane with at least 1/4 wave length radius (1/2 wave length diameter: ~6 inches for 900Mhz and ~3 inches for 2.4Ghz); larger is better.
Which CB antenna has longest range?
The type of antennas with the greatest range are the stainless steel 102″ whip antennas, which may not be practical for parking in garages, under trees, and so forth. The single center load antenna also has about the same transmit and receive range as the whip.
What is the best antenna for a 50 mile range?
