DIY VHF Marine Radio Antenna

What do you think about this video?

optheatre: Hi, thanks for this video! I made one and it works somuch better than the manufactured one I was using. It did cost me a little more though as the cable wasn't cheap.

One question I have I don't know if you can help me with though. I'm using the antenna on land. Which is better? To use an antenna outside where it exposed or put it inside a roof space which is higher up but enclosed? Thanks

dbldvr navyvet: Need to solder the shield or what he calls braiding as well. that pl259 if it works at all won't work for long. very unprofessional install

boashna: nice

Maxid1: At 8:53 PVC of the devil.

Tim Rochford: Thats an SO239 .

Stuart Duncan: Enjoyed that a lot.Always great to see husband and wife teams.

Sean Ingram: The connector on the back of the radio is a SO-239 Connector.  The connector on the coax is called a PL-259.

Jack Everett: You did not mention flux, what you have there looks like plumbing flux, Your should with tHat size tip heat the connector tip and the copper wire at the same time, then apply solder  with flux core,,, "electronic" type solder. Look up proper soldering techniques, military soldering instruction.  Also the shield should be folded over the ferrule piece that screws in to insure contact or as others suggested solder it. What you have is foil shielded with drain, not braid. As some one else suggested, get the correct cable RG58U that is a braid. This will also give you much more wire for the ground side and terminate in the connector better.  The 2 sides should be matched in length or the center length adjusted for frequency.  the feed should come in at the split.  But for emergency this will at least let you receive and possibly trans a short distance

MELODICACHANEL: cool video .

Gordon Foster: It needs an RF choke on the bottom end to stop common mode currents flowing back to the transceiver.  9 turns on RG58 about one inch dia should do it.

Steve Wright: Hey buddy, good on ya teaching people stuff!  Suggestions - solder the braid inside the plug, or else it will corrode up pretty quick and it will be hard to diagnose that fault.  Any ol coax from the junkbox will be perfectly fine, and some of the 75ohm cabletv coax is actually a really high quality item!  Try also to use flexible inner instead of solid, coz it will snap off inside the plug etc.  Keep the vids coming! :)

tom7601: The cable plug a PL-259. The mating socket is an SO-239... :)

Shannon Duffy: Hi there it be interesting on learning to build a uhf antenna with simular stuff. How would i be able to do it?

Mr. Midshipman: LOL, I like those 99 cent serrated "Harbor Freight" scissors you got there.

Shannon Duffy: thats cool i got a 1 meter 10cm pvc pipe a 15mm and some coax cable will try and let you know how i went

SV Seeker: The PVC pipe does not matter at all. You just can't change the length of the exposed wires without knowing what you are doing, and I do not know what I am doing. :)

Shannon Duffy: Would it matter if the pvc pipe is shorter if i built one of these?

Mark Mcnutt: The PL-259 is the male, the female UHF connector is a SO-239. Ironically, the "UHF" connector is less than ideal for UHF. The PL-259/SO239 is better suited for HF bands. Breast vidz. What was the VSWR like?

OnionHerder: thanks mate just that we had a guy come in the other day and he is using the same design and we had it On our SWR meter and the lowest the the reflected power we could get was 7 watts reflected cheers mate ...

SV Seeker: Sorry, no idea. We only used to the talk a short distance from a submarine to shore.

Shrimps: Thanks man, I appreciate the feedback. The reason I was able to get sales is because I offer rare shrimps for sale. Not many other online place is willing to take the risk at shipping high priced shrimps. That is my way of earning online.
