Don't Buy Cheap Cable
!
What many folks fail to realize is that poor quality antenna cable will cost you all the gain you obtain from installing an external antenna or relocating your antenna to a better location.  Badly made or wimpy 1/8 or 1/4 inch cable can cost you up to a Db a foot!
Most of the listings for LMR400 cable here on eBay are not.  When you read carefully you will find that the cable is not Times Micro, Not made in the US, and not guaranteed by a free return shipping policy if it doesn't meet your needs.
Is the cable you are looking at Described as
"Compare to" "Replacement for" or "Same as" or even "Like"
LMR400 or some other certified standard?  This is common with poor quality cable made in Mainland China or some other lesser known locations.  Our Times Microwave LMR-400 cable is US Made, tested and certified to ensure you will maintain the boost in signal from your quality antennas. 1/2 (.405) inch Cable is perfect for runs when you don't want to loose signal strength but it isn't cheap, so please choose a product that will last for 20+ years and give you the service you require.

We have many listings for cable sets with different connector configurations.
We will also professionally replace connections as needed with high quality SMA, BNC, RP-SMA, N, RP-TNC, FME or TNC ends in male or female and customize cable to any length for your needs.
Cable that fails to meet name brand manufacturers standards is not destroyed but is sold as generic, off brand or "house brand" cable all over eBay. Just ask the seller where it's made...
Too much attenuation or signal loss?
send it back
.  VSWR too high?
Send it back
.  Please see the fine print!
The Fine Print
:
If you cut it up you keep it.
Cable should be in "like new" condition, teeth marks/burns/slices etc. are not acceptable.  Please don't run it up a tower and scrape/fray it then change your mind.  Run all tests while still coiled.
If we have installed custom connectors we will not refund the price of the new connector we installed for you.
If
you
have installed custom connectors we will not refund what you paid for them.
Straight or Reverse Polarity -
Big Difference
!
At one time all connectors were straight.  Boys were boys and Girls were girls
then along came the Government...
In order to regulate WiFi and try to create connectors specialized for it's use we have the FCC and the wonderful concept of RP (Reverse Polarity).  Now we have Females with Male Pins and Males with Female innards.  See the picture above of SMAs, but TNCs, BNCs, Ns and others can all be Straight or RP depending on their use.  If you don't know which you need
Please Ask

LMR-400 Coaxial Cable Info
Cable for most all CB, Ham and WiFi installs needs to be
50ohms;
cheaper cable not meeting this standard or cheap mismatched connectors significantly increases signal loss.
It is more expensive to manufacture 50ohm cable than 75ohm, so many cheaper producers tend to substitute without telling or use cable with variable dielectric thickness and copper alloys less than 95% pure for poor conductivity.
LMR-400
Coaxial cable should not be confused with other
s
used for carrying lower frequency signals such as
audio signals or Cable TV signals
. TV  and Satellite type  cable is similar in that it consists of a central wire or wires surrounded by a tubular shield conductor, but it is not constructed with the precise conductor spacing needed to function efficiently for radio frequencies.
Coaxial cable design choices affect physical size, frequency performance, attenuation, power handling capabilities, flexibility, strength and cost.  Skinny cable has less metal to conduct your signal and causes more loss.
Cable MUST be precision manufactured with precise standard spacing between conductors to avoid significant signal loss.
Quality control is Key!
============================================================
Cheap thin cable can result in even the best antenna being worse than useless
.
Signal losses are frequency dependent
, the losses becoming
higher
as the frequency increases. It is not unusual to experience 5 times as much signal loss at 6 GHz than at WiFi's 2.4 GHz.    Installing a 15Db gain antenna and running cheap antenna cable can result in cable loss of twice your antenna gain.  Don't bother buying a good antenna if you are running cheap cable. Losses can be reduced by
increasing
the diameter of the cable.
A cable with twice the diameter will have half the signal effect resistance loss.
Assuming cable quality is equal, the larger cable would
halve
the dB/meter loss. In designing a system, consider not only the loss in the cable, but also the loss in the connectors. Cheap connectors give you as much loss as cheap cable. On a final note, poorly made LMR600 "type" cable can have a greater signal loss than good LMR400...  (See the cable chart below.  Run the largest, best quality cable you can afford.)
This is Top Quality
LMR400 50 Ohm Cable
.  All common Radio Frequency (RF) devices CB, Ham, WiFi, Packet Radio, etc. are to be used with 50 Ohm cables and connectors.
75 Ohm cables and connectors are designed for low frequency signals like Video or Cable TV and are unsuitable for
most
all RF installations
.  Each type of coaxial cable has a
characteristic impedance
(
resistance
) depending on its dimensions and construction, which is the ratio of the voltage to the current in the cable. In order to prevent reflections at the destination end of the cable from causing standing waves. The equipment "appears" electrically similar to a continuation of the cable, preventing reflections that cause signal degradation.
In high quality cable the dimensions and spacing of the conductors are uniform.
Any abrupt change in the spacing of the two conductors along the cable tends to reflect radio frequency power back toward the source, causing a condition called
standing waves
. This acts as a bottleneck, reducing the amount and quality of the transmitted power. To hold the shield at a uniform distance from the central conductor, the space between the two is filled with a plastic
dielectric
designed to maintain the proper spacing between conductor and shielding to assure maximum signal transmission and lowest loss.  Manufacturers specify a minimum bend radius, to prevent kinks that would cause reflections.
You should allow three inches of cable to make a 90 degree turn in your runs without causing signal loss.
The connectors used with the coax must also hold the correct spacing through the body of the connector to avoid signal loss. The transmission of energy in the line occurs totally through the
dielectric
inside the cable between the conductors. This cable can be bent and moderately twisted without negative effects, and can be strapped to conductive supports without inducing signal interference.
LMR-400 cable is designed for outdoor applications, can be direct buried, and the outer jacket resists
ultraviolet light
and
oxidation
. There is no environmental restriction on use for indoor installations.
International Customers
We will Gladly ship to most Countries pursuant  to the following rules:
EBay Customs Notice for International Buyers
:
(In compliance to EBay International Sales Instructions)
We have never had a package held up or taxed by Customs but there is always a possibility.
International Buyers
– Please Note:
Import duties, taxes and charges are
not included
in the item price or shipping charges. These charges are the buyer's responsibility.
Please check with your country's customs office to determine what these additional costs will be prior to bidding/buying.
These charges are normally collected by the delivering freight (shipping) company or when you pick the item up – do not confuse them for additional shipping charges.
We do not mark merchandise values below value or mark items as "gifts" - US and International government regulations prohibit such behavior.
ALL international shipping is done via USPS Air Mail. You can check the rates for your location at USPS.Com and just add to the direct cost to pay for our packaging and transport. I can ship other ways but the cost is
much
more expensive.  Shipping to Canada is double for signature items with tracking numbers and delivery to Europe and Australia is more than triple the USPS Air Mail cost.  In most cases it is not cost effective to buy my items and pay three times the price to ship them...  For more expensive items over I will offer the option of tracked shipping but in most cases you will be better off buying locally
