    I'm just glad to see someone is actually experimenting with antennas!

    I agree that it likely wouldn't be durable and that's what prompted me to go the tubing route. The center insulator will be Delrin and adjustable so the spacing between top and bottom can be varied.

    If you take a little bit more time and effort, it shouldn't be flimsy and should last quite a while outside :) I have an old ARRL Antenna handbook, from 1968 and many of the complex aerials, such as quads and the like, are made using wood - they are even for HF, so are much bigger than the linked one.

    I have to confess, that I don't see the point of such an aerial - at least where I live (Finland), the metallic tape and plastic tubing would cost more than aluminium tubing. Also, Al tubing is just as easy to work with and to make the feed point, you can either use the method shown in the link or drill a small hole and use a screw for a more permanent/reliable fix. The centre joint piece can be short length of plastic tube or wood. I do "get" some of these "cheap 'n' cheerful" aerials, such as using copper tape on a backing of paper or card to make a "roll-up" Slim-JIM or a light-weight portable quad antenna, but this for one, I would say to use aluminium tubing.

    UPS was running really late today so maybe I'll play with it tomorrow. I have an MFJ-1402 on my truck so this will probably be up at our cabin. Our cabin is at 962 feet and I will be putting it on top of a tree that has been topped off at about 20'.

    Thanks for the reply and the advice. When I transmit, it is switching to the correct offset. COMPLETELY frustrated, I took it to the local radio store to have them confirm I am not doing something wrong. While they basically blew me off, because I bought a replacement antenna from them I think they felt a little obligated to at least try. They tuned their radios and could not reach and UHF towers either so they said “maybe all the towers in our area are down from the recent lightening storms.” Not sure if that’s the case but at least it looks like maybe it’s not me???

    Not being totally familiar with Baofeng (I have one but don't use it) I took a shot in the dark and missed. Now I'm going to take another shot and see if might help. I followed all your steps on my UV-5R and you seem to be doing everything correctly. Try this: Watch your screen when you transmit. If your programming is correct, you should see the frequency jump from 444.3500 to 449.3500. If it doesn't, you have not programmed the transmit frequency into the radio correctly. Check your frequency step (Menu item 1.) I like mine set at 5.0 KHz. And, yes. If the repeater was digital you could access it with your VX-8, but all you would hear if someone responded would be static. Same with the UV-5R.

    Correct me if I am wrong but if it was digital I wouldn’t be able to access it with my Yaesu VX-8DR.....right? Sent from my iPhone using Tapatalk

    Is the tower capable of repeating your signal, it may be digital only. Search online for the callsign of the tower, you should find access details easy enough...

    Hi everyone. New member here, and new to amateur radio in general hailing from the garden state. I've always been the type to wrap my head around something until I figure it out, and this time its the airwaves. I am squeezing my technicians course in between some other studies but I picked up 2 Kenwoods to play with in the meantime. A handheld TH-D74A, and a mobile TM-281A. I'm looking forward to the many ah-ha moments as I get going, and plan on scanning this site regularly. Thanks.

    probably okay, no worse than a cheapo mobile once adjusted, maybe you should look on youtube for the pvc cubical quad for 2 meters, thats what I'mm looking to use for my portable.

    I see my last reply hasn't been approved but I'll post this anyway. My aluminum tubing should be here tomorrow and if I have time I'll start putting the antenna together and post pics

    Everything has a price, and usually better costs more. I have an Ultimax reeled up in the shack for a last resort antenna because it receives much but transmits little, I bought a Chameleon Antenna CHA-HYBRID several years ago and haven't looked back. They just work. Mine has a 1/8" stainless cable 66 feet long that I made to allow the Hybrid to be suspended above the shack. I have worked every band and while it is still a compromise antenna, it's the best bang for the buck out there. I would have saved a lot of money had I found these first. I also have a Hybrid mini in my go kit that I take on vacation and find it performs equally as well. I would have to write a book to explain all of the antennas I have tried and the money I have parted with both buying and building antennas over the years. Yes, you will get on the air with an Ultimax or any other such antenna, and no, even a chameleon won't match a beam up one wavelength in the air,

    Welcome aboard Don! The Icom 7300 is an excellent starter radio. Heck, it's nicer than what I run here in the woods. The web based SDR's are another resource to do your initial listening to. Just choose where in the world you want to eavesdrop and you're off. Good luck with the club scene, some are all that and the rest aren't. You'll see, but hope you can find a good one right off the bat. Enough curmudgeonry from me for now, glad you took the time to say hi here. These folks are a good bunch overall. Take care, 73. Eric

    I'm going to give it a whirl and see what happens. Ordered some 1" Al tubing from McMaster today so should be able to start on it by weekend. I'll let you know how it works.

    OK here is some more brainstorming to go along with my original ground plane question. Let's assume I am not going to use a ground lead to any chassis ground as originally stated. Let's also assume that I will isolate the antenna from the bracket in the above image so it is not a functional part of the antenna but only the structure it is attached to. I am devising a spring mount for my ham antenna and need some guidance. Why is it so hard to find spring mounts for ham, or am I over complicating this too much? On the left in the attached image is a design that would use the existing antennas PL-259 mount, and the right side with the black spring is if I were able to omit the bottom portion of the antenna. Does that bottom portion with the PL-259 mount on my antenna (Tri Band, 2m/1.25m/70cm) have any function, and can it be deleted in my design?

    Hello All, New HAM here and new to the forums. I have always wanted to get involved in HAM radio and never really put my mind to it. I have an electronics background so radio theory, superhet receivers, etc is a no brainer for me. I restore vintage receivers as a hobby and have a small electronic lab setup in my garage. So I grabbed the ARRL books and read them cover to cover over the last week and took the Tech and General tests on Thursday and passed them both - now just waiting on my license. I picked up a cheap BaoFeng HT and a NESDR package and have bene playing with them listening only just to see what is out there. I am in Central Florida and there seem to be many repeaters near me and a local club that I will join in October at their next meeting. Studying up on radio options and antenna options and leaning towards the ICOM IC-7300.

    Thanks for the reply, I really appreciate it. To answer your questions, yes I am using 5.00Mhz. I am actually entering everything by hand on the keypad as follows..... - Press VFO/MR button to ensure I am in Frequency Mode - Press the band button to ensure I am in UHF mode - Enter "Receive" of 444.3500 as per the "Repeater Book" reference - Navigate to menu 13 - T-CTCS and enter 110.9 for the tone - Navigate to menu 25 - SFT-D and enter + - Navigate to menu 26 - Offset and enter 005.000 What is really confusing to me is the fact that it works flawlessly in 2m. Using the same process as above, I can hit VHF repeaters 22 KM away clearly with the stock antenna. When I switch to UHF.....crickets!!

    Again, thanks for the replies. I am in the US, North Carolina. KN4WHN. I'll check out that website WZ7U. I'm just getting my feet wet, and I probably should have taken some classes. I'm trying to see if I can ping a buddy across town, as a just in case. That's my main goal right now. Plus the handhelds are becoming pretty popular on the trails. I went on a 4 wheeling trip to Colorado this past summer, and CB's were fine, but sometimes you need to reach out a little further. I figure I can program just any frequency in on the Baofeng, and use that while trail riding, they even come preprogrammed with a few test channels. I want to do it the right way though.

    Most certainly will need to keep tolerances exceptionally tight at these frequencies for maximum bang. Precision fabrication at its finest!
