I use a baby tar heel on my car. Works very well. Had it on my truck and it didn’t work as well.

love the disclaimer! im abandoning the 160 for the moment. not forever, just for today. and maybe today for the next couple months.

if theres no connection to the feed point then its a parasitic element and thatd be through induction then?

I had a jpole mounted on the hood of my car. Works great.

good point

i know yall have read and gotten tired of reading me talk about the antenna. but here goes, after i took the mfj913 current balun down i went ahead and cut it apart. here it is. would it have cost all the much more to use insulated wire or just anything to keep it from shorting out? depending on...

i bought a chinese amazon autotuner. worked great till it didnt. replaced it and its all good. but back to the one that dont work. powers up, self tests, 9.99 swr in bypass, auto will not tune. it goes into tune and just locks up. will reset. checked diodes under swr bridge and they seem ok...

131.5' antenna cut at 70/30. 4:1 ruthroth balun at feed point 100uf 3k volt disk cap fed through between balun and long leg 1:1 Guanella coax choke below balun 106' rg8x coax 40' kinda sag flat top.

would that be considered a capacitance or inductance antenna? how well did it work?

trashed that one. tried a 60/40. didnt care for that too much. i decided to go back to the 70/30 split. to gain 15meters i went up on 20 meters and i have not been a big 15m fan for the most part. however i can use a tuner if i really want to.

blue line is no calibration for the vna. sees all from end to end green line is a calibration that sees only the balun and the antenna. not concerned for 15m all that much. 80-20 split caused too much rfi here at the house.

oscillator warming up? sounds like its out of alignment and as it warms up it starts to pull up

Anf is off. As is nr. And when running the nr I keep it lower than 4

yeah im a pest. i know. my wife reminds me daily. ive always been a yaesu fan but i picked up an icom 718 that has the dsp filter installed. its alright. it aint no yaesu hahah. alright anyway, some signals are crystal clear but some have an almost digital sound quality to them. ive turned the...

I have my choke right below the balun. And I’m about convinced my mfj balun is goofy. I’ll have new cores tomorrow and just wind my own.

So ladder line. Uh shielded ladder line. It’s a mystery! Hahahaha. Not a bad idea though.

Unfortunately I have no ladder line. Been playing with coax and chokes and baluns.

Has anyone got any input on using a 260’ long dipole cut for 1.8mhz as an all band antenna?
