Oct 18, 2015 · I use LMR 400 bury cable, excellent in it's longevity over RG6 as well as lower loss, esp in the 800Mhz region. It does not matter if one is transmitting or receiving, a micro-volt signal impinging from feed point to your HP is still transmitting a signal.

Nov 2, 2020 · For myself, I've run LMR-400 equivalent (Air-802) from my antenna to the filters and multi-coupler. Then I run RG-6 from the multi-coupler to the receivers. The difference in loss for the short distances is small, and RG-6 is certainly more physically manageable.

Mar 12, 2023 · Flexibility: RG6 is more flexible than LMR-400, which can make it easier to install in tight spaces or around corners. Impedance: Both RG6 and LMR-400 have a characteristic impedance of 75 ohms, which makes them suitable for …

Aug 30, 2023 · In this article, we will delve into a comparison of four popular coaxial cable types – two Radio Guide (RG) types, RG6 and RG58 – as well as two Land and Mobile Radio (LMR) types, LMR240 and LMR400.

Mar 18, 2023 · LMR 240 75 has an attenuation of 6.9 dB/100ft at 1000 MHz while RG6 has an attenuation of 10.1 dB/100ft at the same frequency. This means that LMR 240 75 can transmit signals with less signal loss than RG6, making it a better …

Jul 10, 2020 · Amateur radio operator here, speaking from direct experience: LMR400, preferably with professionally installed N connectors, is well worth the extra cost & hassle. RG6 is simply too lossy for use at UHF & higher frequencies.

LMR-400 is available with a lower loss dielectric (Foam PE). The 146 MHz loss through 100 feet of this cable is 1.5 dB, or 0.9 dB better than ordinary RG-8U. A loss of 1.5 dB means that we still lose 30% of the power.

Oct 21, 2020 · LMR 240: This .240 inch OD cable is an improvement over 8X, adding foil shielding to obtain lower loss figures. The Ultraflex version is easier to work with and suitable for use with antenna and rotator combinations.

LMR cable sizes range from LMR-100 (2.54 mm) to LMR-1700-DB (31.75 mm). Because of its flexibility it can be used as small size feeder cable in place of larger corrugated feeder. They exhibit better attenuation property compared to RG cables for wireless applications.

Today, we're comparing the RG213 and LMR400 cables. RG213 and LMR400 are both coaxial cables that have a wide variety of uses. Although there is a significant number of overlapping characteristics between LMR400 and RG213, there are a few differences that set them apart.
