@tt12514 Μπορούμε επίσης να καλύψουμε τις ανάγκες σας σε κεραίες και φίλτρα μη συνηθισμένων συχνοτήτων. Αν έχετε ανάγκη, μπορείτε να επικοινωνήσετε μαζί μου στο email: aprilai869@gmail.com.

Υποθέτω το αλιεξπρες προσπαθεί να καλύψει την ζήτηση του πολέμου σε δέκτες βίντεο που λειτουργούν σε "μη συνήθεις συχνότητες".

@tt12514 We manufacture a wide range of antennas for electronic warfare applications. Please feel free to contact us for inquiries.

Quote "The enemy is reducing the FPV control frequency, and the size of the EW antennas is increasing. Attached is the previous photo. FPV Kuznechik with a control frequency of 230 MHz"

@tt12514 Interesting insight. By the way, we also manufacture this type of patch antenna. If you have any needs, feel free to contact us at aprilai869@gmail.com.

@SagoLabsVC money is precious, yet freedom is more valuable.

Financial freedom isn't about buying everything you want. It's about your time not being for sale.

@pe0sat @oktayegi @AMSAT @NASAArtemis We can make it. Could you please share some key parameters? For example: frequency range, noise figure, gain, supply voltage, and connector type. If not sure, just let us know your application. Or you can send me a private message.

@April_AI2026 @oktayegi @AMSAT @NASAArtemis Looking for an affordable filtered low noise S-band LNA

Last night I received the Artemis-II signals with a small 60cm Offset dish. At 01:30U a wide band (+/- 5MHz) signal was activated and around 03:30 I see a residual carrier following the predicted orbit. Let see if we are able to detect the signals again. @NASAArtemis

@ibelings nice design

Ever wonder how the Long Wavelength Array (LWA) images the invisible low-frequency radio sky in real time? 256 cross-polarized dipole antennas are spread across a ~100 m field. Every element is digitized with precise phase coherence. The system then computes cross-correlations for all antenna-pair baselines, sampling the uv-plane with visibility data. A fast inverse Fourier transform (IFFT) converts those visibilities into stunning all-sky images — revealing the dynamic radio universe at 10–88 MHz, updated every few seconds with 100% duty cycle! Live all-sky view here: leo.phys.unm.edu/~lwa/lwatv.html 🌌 Long Wavelength Array (LWA) は、目に見えない低周波電波空をリアルタイムでどうイメージングしているのか？ 約100mの範囲に展開された256本の交差偏波ダイポールアンテナ。それぞれの素子を位相コヒーレントにデジタル化。全アンテナペアのベースラインについて相互相関を計算し、uv平面に可視度データを埋め込みます。高速逆フーリエ変換 (IFFT) で可視度を全天画像に変換 — 10〜88 MHzのダイナミックな電波宇宙を、数秒ごとに100%デューティで映し出します！ ライブ全天映像はこちら：leo.phys.unm.edu/~lwa/lwatv.html

@_XE1L Can this antenna withstand Beaufort scale level 10 winds?

Mods in the station continues, #6m #LFA homebrew antenna is now on place. Hope it works better than before.

@ON4DPX fascinating setup

Getting ready for some fun between the stars !

@YD9IPB @vu2lbw @nitin_vu2jek Long-distance communication up to around 5,000 km can also be achieved through HF communication using antennas such as dipole or long wire antennas.

Thank you for the QSO 🛰️ LEO FM seems to be the furthest contact 5000+km @vu2lbw @nitin_vu2jek 🙏🙏🙏

@oktayegi @pe0sat @AMSAT @NASAArtemis We customize a wide range of antennas for various applications and environments. Solutions can be tailored to your specific requirements—feel free to contact me if you have any needs.

@pe0sat @AMSAT @NASAArtemis Well done sir. What is your setup? Best regards.

@rf_hacking We can design RF filters with even lower insertion loss and provide customized solutions tailored to your requirements.

The excellent sysmocom's L-Band cavity filter 1525-1705 MHz is back on sale. This is not an advertisement. The filter is truly one of the best you can buy. Insertion Loss <= 1dB. shop.sysmocom.de/L-Band-cavity-…

@rf_hacking interesting design，inside this inflatable sphere, is it a parabolic reflector antenna? Does it focus the signal through the parabolic surface to achieve high gain and directional communication?

@antennatestlab interesting design, so cool

LEGO Horn Antenna, part 2: It works in C-band with about 12 dBi of gain. Tested two lengths as shown. The conductive bricks are sold by antenit.com starting at around $7500 for a kit! Also, these are not LEGO branded blocks.
