Here are some numbers via the Times Microwave Coaxial Cable Loss Calculator for 100 feet of cable: Cable Loss (dB), 100 feet To put this into perspective, if you're running 100 feet of RG-8 or RG-213 and are thinking of upgrading to LMR-400 because of the loss you're incurring, think again, especially if you mainly operate on the HF bands. https://www.timesmicrowave.com/documents/resources/LMR-400.pdf]. Been in service for over ten years now. This coax cable provides excellent performance for high power HF needs or VHF/UHF applications. But because the circuit requires a 20 percent safety margin, the circuit needs to provide at least 27.48 amps (120 percent of 22.9 = 27.48 amps). Surely the answer will be no. At 460MHz, 2.7dB of loss, a bit less than 1/2 your signal lost in the cable. I talked with a Times Microwave technical sales specialist and here is his answer regarding bends: You can bend the cable to a 1 radius and leave it. A mini-fridge may only need between 100 and 300 watts. What is the wattage rating on LMR 400 ??? LMR-400-75 is the 75 Ohm version which is ideal for . However, my SWR for 20M is a whopping 16.4. Coax, oh the other hand, is very lossy at high SWR. Depending on the length of the run, there honestly isn't much difference at HF. Two parallel diagonal lines on a Schengen passport stamp. A tuner doesnt fix anything on the line, it just transforms the impedance that exists at the point where its connected, to 50 ohms on the radio side. Now the answer that you are looking for: What will a 400-watt power inverter run? It has a ten year warranty so if you break it down to yearly cost it's kind of affordable. I work in the commercial 2way business with Motorola, and I have found a fairly significant difference in connectors in regard to losses.

This antenna is 140 ohms or so both on 14mhz and 18 mhz. I ran an 8 pill thru it (1500 bird watts) and it melted like grilled cheese. The significant advantage here is that the cable keeps its excellent loss figures compared to the UF cable, which is around 15% higher attenuation due to the stranded centre conductor. Their transmission line is very high quality and made to strict standards. required. Wow looked all over for a power out vs in chart and finally found this page after spinning my wheels looking for charts. Fortunately, I have a Palstar AT2KD tuner (awesome piece of gear) and I can tune 20M down to 1.7 SWR. That is also why you need to know when to upgrade your service panel. See the edit to my answer. That site does not state the K1 & K2 factors, so I cannot add it to the calculator. If we take a look at any RG style coaxial cables, the LMR-400s offers very significant advantages in size, weight and electrical performance. But Im no expert on fan dipoles, so read elsewhere to find people with more experience with them. I will buy it again when I redo my cable run. Is it possible for you to spend half an hour without your cell-phones? Personally I take those figures to mean that it's OK to bend the coax to a 1 in / 25.4 mm radius during installation, but it's not OK to leave it like that; it should be left with a radius no less than 4 in / 101.6 mm. RG8 is a thicker 50 ohm cable, at 12 AWG, that can provide a stronger signal than RG58. Before purchasing a 400 watts power inverter, people asked a lot of questions.

Thanks for your tool but I dont get it when I check the values, it does not match exactly specs. applications where an amplifier is not used. cant a balun be made for 23cm ? https://www.ad5gg.com/2017/07/24/lmr-400-for-ham-radio/, https://www.awcwire.com/productspec.aspx?id=m17/74-rg213-coaxial-cable. I have it bookmarked to find it easily when i need it. And in the case of ladder line, SWR on the line doesnt hurt a thing. explore the world through the prism of knowledge. You can look for an inverter that has Remote Control features. Saw a video a while back where a guy strung about 30 various adapters together, and was very surprised to find the total loss negligible. For example, if you have a fairly small 800-watt microwave oven, the electrician will normally install a 20-amp circuit even though a 15-amp circuit can easily handle this appliance. I have 30 What are the implications of pulling LMR400 through EMT conduit with several 90 degree conduit body fittings, https://www.youtube.com/watch?v=5AgFum5K7bw, https://www.timesmicrowave.com/documents/resources/LMR-400.pdf. Harold Melton (kv5r) I have a fan dipole up for 160, 75, 40 meters on 160 swr is fine it is 100% but on 75 I cant get the swr down lower than 1.7 and on 40 meter it`s about 3 swr I tried to make the legs shorter but it would make them higher swr`s even if I make them longer thy would be higher too it works okay with my antenna tuner but on 160 I don`t need a tuner I can feed it directly to get a 1.1 swr you can tell me what to try or maybe I should get rid of the fan dipole and put up a multi band dipole fed with ladder line if you want I can send you pictures of what I have now give me your message address and I could sent it to you give me some help Harold Melton (KV5R) if I get rid of the fan dipole I then would only have one leg I don`t mind using a tuner but if I have to use a tuner I might put up a multi band dipole it would be okay let me know on what to do.Paul WozniakKB9VWD, Hello Paul, If you use the core for 12 V in chassies wiring you can transfer av load of 228 W. For power distrubuition at 230 V you can load it with 690W. Attenuation: 0.7 dB per 100 ft at 30 MHz and less. Its also popular in the maritime industry, typically used on systems such as 4G Wi-Fi, VHF/UHF radio communications, GPS and TVRO. How dry does a rock/metal vocal have to be during recording? Though the simple answer is anything that consumes less energy than a 400 watts inverter can run 400 watts. RG-174 (50 ohms) is very small (~0.11") and lossy. Example: In the #1 chart for 25-feet extension cords, you can see that a 16 AWG cord can handle 1,430 Watts and up to 13 amps while a bigger 10 AWG cord can handle 2,200 watts and up to 20 amps. What is the best bitrate for YouTube videos? I am wondering what the possible issues would be with using 2 inch electrical conduit with a couple of conduit bodies (small housing with a cover to help pull wire through an angle). Timothy Thiele has an associate degree in electronics and is an IBEW Local #176 Union Electrician with over 30 years of experience in residential, commercial, and industrial wiring. also, honestly, what's up with the caps lock? Well, a small-sized blender will take 200-400 watts power to run smoothly. A large microwave oven with a built-in vent fan and light fixture can easily demand 1,200 to 1,500 watts of power, and an electrician wiring a dedicated circuit for this appliance would likely install a 20-amp circuit that provides 2,400 watts of available power. An odd-quarter-wave feed-line will transform that to a low impedance, but then it wont work on its fundamental. See KV5Rs Coax and Ladder-Line and ERP Calculator! Older homes that have not had their wiring updated often have such appliances installed on circuits shared with other devices, and in these situations, it is quite common for circuit breakers to trip or fuses to blow. by RollingRadi Wed, 22 Mar 2000 04:00:00. saves time looking all over from different manufacturers, some of will not let you print info. 2. Double-sided tape maybe? You need at least 3-4 times the line width of spacing, so for half-inch line youd need insulation 3-4 inches in diameter (0.5 x 4 x 2).
