OMG What an Improvement!

2023年1月6日 - 已在美国亚马逊上发表

已确认购买

I'm a 3rd floor apartment dweller using an AirSpy HF and an 8ft horizontal dipole. I hooked up the MLA-30+ and OMG What a Difference! My noise floor was -90dB and with the MLA-30+ amplifier, it is only -80dB. A signal that was burried in the static with less than 10dB S/N ratio was too faint to pull in. Now with the MLA-30+ I have 45dB S/N ratio and the signal is booming in. I have homebrewed and purchased many antennas but this one beats them all - hands down. Tomorrow I build a PVC stand for it. Abosolutely Thrilled!

K-180WLA

2022年3月8日 - 已在美国亚马逊上发表

已确认购买

Let's be clear, this review is about the K-180WLA and NOT the MLA-30+. First, I had the MLA-30+ several months ago. It never performed correctly. I think it was defective. Not saying it's a bad antenna, just that my unit wasn't up to specs. However, I do believe it is a fantastic little antenna. SO, I decided to go ahead despite the reviews that are very critical of the FM overload problem on the 180WLA and purchase this antenna. I live in a rural area and overloading is not a problem. the 180WLA is attached to my Airspy HF+ Discovery. I am very pleased with this antenna and it's performance with the HF+. It performs just as well as my 132 foot end fed wire, and my YouLoop with an LNA. Sometimes it outperforms these other antennas. It is a good match for the HF+ insomuch as the HF+ is a very sensitive receiver and matches well with active/amplified circuits of the 180WLA. The noise floor is noticeably lower with the 180WLA. I do have the 180WLA mounted outdoors at a height of about 20 feet. Having said all of this, I can see where the 180LNA in an urban environment, or indoors, would be compromised by FM overload and indoor noise. An FM inline filter like the Nooelec Flamingo would probably help this antenna in that scenario. In summary, this antenna performs as well as the MLA-30+. The bias tee with battery is very good and you know your are getting a clean power supply to the LNA on the pole. I use it every night and recharge the battery every few days. It has never gone dead on me. I recommend the 180WLA if you don't have FM overload in your area or you have an inline FM filter you can add to your feed line. The mounting hardware is great and the other accessories add value. Thanks.
