EFHWアンテナ調整がちゃんと取れてるからATUとか入れなくていいので精神衛生上とても良いです。 #EndFedHalfWaveAntenna #EFHW

New video up: Field testing the N9SAB 80 m linked EFHW as a low horizontal 40 m NVIS antenna. One watt FT8, RigExpert measurements across four bands, and a practical short range Winlink NVIS connection. Watch: https://t.co/YZRZOm5zjq #HamRadio #NVIS #EFHW

There’s a new guy in town! 😎 Look underneath my rig: I added an mAT-Y200 Automatic Tuner! I’m using it to "cool down the heat" on #WARC & 80m which aren't "natively" handled by my 40-10m #EFHW. Taking #SWR from ~2:1 (worst case) down to 1:1! 🔥➡️❄️ #AmateurRadio #HamRadio

My homemade common-mode current choke: 4"×4"×3" junction box, 2 1" holes drilled with a paddle bit (to get the PL-259 through), 2 1" rubber grommets, FT240-31 ferrite toroid core, waterproof duct tape to seal grommet-to-coax junctions. Installed 1' from the end. #HamRadio #EFHW

Pour ceux qui aiment les chiffres, voilà le tableau recap de mes tests entre le dipôle (en rose) et la #EFHW (en vert). En gros, le dipôle apporte une amélioration de 3 dB au SNR. #radioamateur #antenne

#EFHW 給電部コンデンサーの値を変化させ、SWRの周波数特性変化を見てみた。75～100pfが良さそうだ。給電部コンデンサーを75pfで固定して、負荷値を変化させた時、SWR特性がどう変わるかも見てみた。値が低い側へ変化は弱そうだが高い側へは強そうだ。FT-114-43へ22回巻3回目タップ #pota #nanoVNA

my covert EFHW for 40,20,15,10 and tunes 17 on the FT710 internal tuner. swr 1.5 to 1.8 so not bad. Build material of my parkhome walls probably doesn't help as it's foil insulated. Works a treat though. #radio #hamradio #amateurradio #antennas #efhw
