so did you make the mla loop bigger and what did you use for the loop?? or did you leave it as stock? - good results though - i plan on doing the coax mod my self when the BNC fitting arrives next week 👍👍
I Used Similar Materials, I Just Used Copper Pipes With Silicone And It All Made It Weather Proof And Vibration Proof Because Of The Silicone, Put The Vertically On A Fishing Pole And Fishing Pole Into The Mounth In My Third Store Of The House :)
When you say the noise floor is lower or higher- how do you know that the difference is not in the actual noise floor but differences in the gain of the 2 different antenna amplifiers? The only true test is to compare signal/noise.
Hi thanks for this video, do you have a link for the aluminium rods pls or a part number at screwfix, 2nd question, how would I then connect this to my Grecom hand held scanner please? Sorry for the noob questions, thanks.
Wow. Looked amazing. My wife has bought me a aerobatic flight experience through virgin and Tatenhill is one of the options. How long was you up there for?
Hi it was forty minutes I believe it is usually thirty but as we had some storm clouds in the area the pilot took us to a clear area before the real fun began, the staff at Tatenhill were brilliant and can highly recommend them,
Great tool with many applications to comer. But you will never control all this from a flimsy the touch panel. We should ditch the display and connect this to a chromebook via USB.
Putting a bigger loop on the MLA-30 makes a big difference. My antenna for example receives down to around ~20KHz. Submarine communication DHO38 on 23,4 KHz, the British time signal on 60, the German on 77,5 and a couple more at night and day. It's basically a homemade YouLoop with 3 m circumference on the MLA-30 amplifier. Still goes up to around 30 MHz.
Page 65 of my old 1970 ARRL Antenna Book defines a "small loop" antenna is one whose total length is short compared to the wavelength received, so even a 3 m diameter loop qualifies as a "small loop" at LW. On the same page, it says that small loops "are widely used at frequencies below the standard broadcast band for direction finding." If small loops are directional, do you have a way of rotating your 3 m diameter loop? I am pleasantly surprised to read that your MLA-30+ amplifier works at LW frequencies. I have read that the MLA-30+ is not very directional at HF frequencies. How directional is your 3 m loop at HF? Thanks!
A reasonably fair assessment, though you tend to try and explain the difference when the MLA is better than the Wellbrook. The other way around, you say "as expected" of the W/B. Also, the MLA-30 is beyond its design range below 500kHz, so the comparison is not valid.
Doesn't it have a touch screen? Also, you should look at SWR and impedance of the antenna. You want your SWR as close to 1.00 as possible (<1.50 is good) and your impedance to be the same as your receiver and cables (usually 50ohms)
What happens if impedance is different? I have a cell phone signal booster. It works at 50ohm impedance. But coax is 75ohm. What would happen in long term or short term?
New to the hobby Just subscribed to squawker fantastic program using the Uniden UBC3500XLT with freescan is there plans to add this to scanner integration. Thanks
Yes,although you will likely miss some transmissions. If you can scan at 12.5 or 5khz that would be better and pick up more transmissions. I also use an older scanner and am limited to 50,25,12.5 and 5khz. Also, depending where you live and what airport's you can receive this may not be much of a problem, I am in south Wales and pick up Cardiff and Bristol airport's, their main frequencies are located on the older channel spacing i.e they have not changed, so reception with old scanners is not a problem. St Athens airfield uses 8.33 but not very often use any newer channels that fit the 8.33 channel spacing. Some bigger international airports and European flights use 8.33 channels more than some of the smaller airports. Also worth scanning for are ground frequencies in the UHF Band if you have decent reception of tower and radar. Here you can hear aircraft getting instructions before takeoff etc. Usually around 460-470MHz. Get yourself a copy of the UKAGF book, the current 2022 version is out and lists all the airports and frequencies. Ofcom website, licence database you can find uhf frequencies that are licensed to airports.
I see you crimp the coax shield and center conductor wires directly to the antenna rod. Is a 75 ohm balum necessary or does it matter . Thanks from the US.
If you divide the difference in performance by the difference in price, then, well, the value for money argument is won by the MLA, hands-down. The WellGood loop is also worth considering at this (and much higher) price point, and may well be better than the MLA.
Hi, regarding long wave. I've tried the Bias-T on my SDRplay and this massively reduced LW signal strength compared to when I used the Biasing Tee that was supplied with the MLA30. I must admit I have the MLA30+ though, but maybe you can give that a try or try a different supply which delivers ~12V rather than the 4.7V that the SDRplay can only deliver.
I ORDERRED THIS DEVICE TO YESTARDAY, I HAVE LIKE 40 DIY ANTENNAS THAT WORK SUPERGOOD, BUT SOME NOT SO THAT WHERE THIS DEVICE WILL COME IN, I THINK TO CHANGE SOME PARTS ON IT LOOKING TO YOUR VIDEO and WOW, this Item for THAT price is soo good, can`t believe it will arive like that! i just can`t wait to test my antennas that im listening to emergency police radios from and to see how good actually is my 17 meter antenna, with 17 meter i mean its 17 meters up in the sky on my 3th Floor Roof, Thats The Last Floor Of My Private House,Its 1M - 3M Antenna Actuallt Im using A Boafeng AND An Sdr's, soon i will make a Workshop For My RU-vid Channel Where I Will make EVERYTHING , I Will Show How To Sufvive On A Minimalism And How To Make Stuff That Actually Works From Random Items And For Noise Reasons I Will bring All My radio Equipment There To Because In My Garage Doest Have Any Electric Items Now On, But There Will be, But When I Will Work With radios, All Will be Disconected, Here In The House I Just Can`t Deal With That Thing, In House I WIll Make Studio At The Same Time Because My Workshope IS in the House Now, But I Will Move It To A garage And The Room Where The Workshop Was I Will Make That Studio For Beatmaking, Music Making And Video Making And Videogame Streamiung And Just Chilling Place,m Like A Real mancave, I Will Make A Car Simulator To From Wood Frame From Logitech Steering Wheel And Pedals And A Shifter, I Will Make It So realistic, I Will Put A Vibrator Motors In The Chair Of The Car, I have A Real Vibrating Chair And I WIll Use Motors From That Vhair To My Simulator :) The Simulator Will be Suspended On Springs ANd Rubber So You Will Feel The Vibrations Much Better Because If The Simulator is On The Ground, The Hround Will Take Most of The Vibrations :) Soo jheah, Best of That, I Will Videotape Everything i do there soo, You Might Wana Subscribe If You Are In To That Kind Of Stuff, Ohh, Yes, Im making Antennas To :) A LOT OF THEM And This Device Will Be A Life Saver For Me :)
A tree rat on my roof ate halfway through my coax cable so now I have to replace it. I'm thinking 35 feet of something better than what comes with it. Ideas please.
good build there, looks nice and light for portable amateur use. I like the connection boxes. one point, I thought the aluminium rods came anodised i.e. no conductivity- did you sand it off first or were they bare aluminium. Barnie M7PBX.
How dare you even suggest this piece of garbage?! Cheap Chinese junk! It can only do 2/3 of things my Tek TTR500 can do! And my TTR500 was only $14,000! If you can't even afford a small price of $14,000, why do you even bother? Radios are for rich people only, get your easily affordable products outta here! I'm kidding, of course, but I see a lot of folks that rag on inexpensive gear just because it's not top shelf and this is how they sound to me as a beginner ham and not very rich person lol. Also I have no clue what a TTR500 can or cannot do, it was just the first model I found on Google.
