Nice catch getting Saba/St. Eustia(?) PJ5/SP9FIH! It’s only ~5 sq. miles/~13 sq. kms.. I worked him while mobile on 8 February. Love the antenna! Sounds like a good stealth setup.
Tim, this is awesome! I'm happy that you had such good success with this trapped vertical. Many new hams watch your channel for advice, guidance and encouragement. I'd like to suggest that when testing SWR, you always announce your callsign on the air. Some may be watching and think it's ok to do this and place their license in jeopardy. Keep up the great work! 73
I was testing a 2m set one day which I had just finished repairing. Where my QTH is in Wales is down the bottom of a valley and you generally can't get anywhere on 2m unless it's through the local repeater (GB3BC). I was transmitting into a dummy load to receive on another radio. I was transmitting "Testing....1, 2...." After a few minutes of doing this, I heard over the air. "1, 2"....! I said hello and gave my callsign - turns out it was another ham who lives about a mile down the valley who had a scanner on, scanning the simplex frequencies! We had a good chat.
Tim,this was a great video!!! Some great contacts there 👌 have you ever thought about doing a video about grounding n how you ground ya shack equipment?? Dont think ive ever seen one done in uk.73
Like all of your videos great Tim. I'm going to try this antenna at home. Is it worth using a .05 wave counterpoise similar to most efhw? Cheers wayne VK4WTN
Can’t tell if or where your coax or radio connects to the car frame. Usually the most important issue is how the “ invisible” half of the antenna is handled.
Doesn't need the car frame. There's no invisible half of the antenna, this is a half wave, not a quarter wave. The outer of the coax will act as a small counterpoise.
As Paul said below as there is v high impedance at the feedpoint the small return current causes no issue for me on 100w. For surety you can use a choke about 2m from the feedpoint
Ah good to see the weather improving and you not freezing in the car anymore Tim . 73.
Thank you John! Spring almost here!!
Nice one, Tim. Simple and effective. You can't argue with those results 👍
Yes great fun!
Good one Tim enjoyed what looked like a good number of QSOs coming through there and a simple practical antenna build
Yes it was good fun and simple .. like me! 🤣

Hi Joe yep it worked well! 73
Brilliant results for such a simple antenna!
Thanks Dom!
Great results. And a VERY light weight portable option.
Thanks mate it did well. A decent option for a contest weekend maybe

Hi Tim another great idea good work well done...😊
Thanks my friend
Nicely done Tim
I especially like the no radials. One thing that stops me taking my Commander antenna /P
It’s certainly makes for a quicker deployment
Great!
Tim,this was a great video!!! Some great contacts there 👌 have you ever thought about doing a video about grounding n how you ground ya shack equipment?? Dont think ive ever seen one done in uk.73
Oooh can of worms there mate!
OK now how about a trapped dual/Multi band 5/8wave? Might as well go for broke I say. Good video thanks Tim.
Nice thinking and thanks!
Like all of your videos great Tim. I'm going to try this antenna at home. Is it worth using a .05 wave counterpoise similar to most efhw? Cheers wayne VK4WTN
You can do .. I find at 100w and a good swr there is little or no rf issue
Good watch Tim 👍
Thanks mate

Hi Tim 👋
Hi Andrew
Great video Tim ! Question: what is the resonance frequency for the trap ? Is it just below 28 Mhz or a bit higher ? 73, Marcel
Hi Marcel it’s just below 28 MHz from memory
@@timg5tm941 Thanks for the fast response !
Hello Tim could you tell me at which frequency your trap resonates ? Ex 21.00 or 21.275 etc, Vince
Hi Vince 27.8 and 20.8
O yeah what wattage was that Tim it looked a bit thin for 100W ..Good if it is though ;-)
100w it was! The wire is rated for 125w pep
Tim: Where did you buy your 10m trap?
From eBay but the guy doesn’t make them anymore sadly
Sorry 28 Mhz etc Vince
Your next mission, should you choose to accept, is to add in 12....
I’m ahead of you .. modelling indicates it might work. However I’m not sure there’s enough wire to play with. I’ll take a look.
