Nice filter testing. I only have 2 band pass filters. 10 and 20 meter 300 watt ones. They work good. I tested with Nano VNA H4 . I have some low pass filters as well. the MFJ 1.5 Kw one and the RM italy one. RM still makes 2 low pass filters. I got a diplexer as well. 1.8 to 30 MHZ in 1 port. 50 to 250 MHZ on 2nd port. It is a high pass and low pass together . I found another way to use it for testing . Put HF amp on common port. watt meter and dummy load on each of 2 ports. Lets me measure 2nd and 3rd harmonic like on 10 meter. I did that for testing a dirty amp. Just something I picked up a hamfest . it's rated 1.5 KW and bigger then anything showed in video. it is at least 2 X the size of that drake. You can use them filters on like one of them KL 203P amps and see how much they clean up 2nd and 3rd harmonic. I have seen AM broadcast traps for 50 ohm feed like. some 160 meter radios gets wiped out from AM stations. Like the G90 . 60 MHZ range would be in the TV VHF LOW band. Still in use . they just switched format from NTSC to ATSC . Only the upper TV channels reassigned to cell phones. I think 3G and 4G . Most TV broadest hear in my part of NY is all UHF . There was some low power analog VHF stations but gone now. Their is a 4 meter ham band in UK around 70 MHZ . 73
It's funny you mentioned the television broadcast band. I just recently cut the cord with cable company. No reason to pay high prices for loads of channels I never watch. I will be going with a standard HD television antenna for local programming ect. My wife asked me in her words. Won't your radio's interfere with television 😂 I said generally everything is so high and frequency now that it's not going to be a problem especially since I'm not running equipment that would really be an issue. There's ways you can stream the local channels but still everybody's out to take your $$$ per month. Since the antenna installers will be coming in a few weeks time to switch out my antennas it's a good time to have them put a TV antenna up there if at all possible since they do that primarily on a daily basis. I just recently picked up a nano VNA. I haven't had a chance to even try it. I really like testing things and seeing how filters work ect. Just something new to play with I guess. Right now I'm playing with a half wave horizontal rigid dipole for 11 m. It's almost in the finishing touches just waiting for daylight today. This will be going up on my tower just below the Solarcon Max 2000 optimizer. 73

What are you asking for the 6kw filter ?
I'll have to think on this.
@@N8MJS. Ok. Let me know. 🇦🇺👍🥃
Will do
So how about that filter ?
