  1. How's about a fold over or a cap. You put the antenna when you have the car. Take it off when she has it? Sent from my SM-G975U using Tapatalk
  2. Yes. It is the reversed. Sent from my SM-G975U using Tapatalk
  3. General rule of thumb. UHF performs better outside in the woods. Attenuation through wet leaves and such is better. Where VHF performs better in an urban setting. It has a better chances of bouncing and penetrating walls/ glass then UHF. Although personally I don't see it nor can say I have seen quantifiable gains to support. They both seam to perform about the same. Sent from my SM-G975U using Tapatalk
  4. Most repeater owners are pleasant. You can try to email them. Ask nicely they usually will say yes. Most also want people to use them. Or simple make a callout on the repeater. You may not even get an answer. The only ones I steer away from are the emcom repeaters. Usually in this area they are run by groups like REACT. Even then they have notes saying REACT members only, or REACT members have priority. Down here most of the repeaters have that one guy who is always monitoring it.

  5. Pretty much it. Think it also had the option for a bit more ram. It really was incremental increase with emphasis on connectivity. Sent from my SM-G975U using Tapatalk
  6. Sounds like you have some buttering up of the new landlords. Sent from my SM-G975U using Tapatalk
  7. Kinda why repeaters get expensive. Its all about the isolation. On tower for the antennas you often see one upside down if it ia close in frequencies. Sent from my SM-G975U using Tapatalk
  8. Yeah rg400 can be tough. I found a easy way. Take scrap 2×4 drill a whole so the center conductor can slip easily through the center. Before you cut the sheath, slip the shrink wrap, ferrule, and the ring. (Using pl259 here). Proceed to cut the coax, slip the ferrule part way on to the shield wiring. Slip on the pl259, place the rest of the shielding around the connector. Take the crimper and gently grab the ferrule. Place the whole thing onto the 2x4, make sure not to damage the center lead. Using the crimper as a vise push down till seated. Finish the crimp and check for shorts as usual. Kinda works for n connectors as well. Sent from my SM-G975U using Tapatalk
  9. Hopefully, they are NOT physically connected to the same antenna at the same time. If they are on two separate antennas make sure there is a lot of separation between the antennas and feedline Sent from my SM-G975U using Tapatalk
  10. Will come down to as mentioned above. How long, how flexible and budget. Nothing like spending $$$ on a high gain antenna to lose all the gain in the feedlines. For short jumpers, where you may want flexibility i go with RG400. Not to be confused with LMR400. I would like to run at least LMR400, but it does not like to be twisted into "s" or other odd shapes. Note the losses on this chart for 450mhz per 100. This isn't even with connectors which can add up. https://www.google.com/url?sa=t&source=web&rct=j&url=https://static.dxengineering.com/global/images/chartsguides/d/dxe-400max_ks.pdf&ved=2ahUKEwj2-4GO8MrsAhV5l3IEHYysDnoQFjAAegQIARAB&usg=AOvVaw105dYs19Vh6HLaokTPN5i8 NOTE: these numbers are with quality know coax. Not some crap you find off of Amazon. I personally recommend Rfconnection.com up the street from here. Price is competitive, owner is a ham who has operating the shop for 40+ yrs. Stands behind what he sells. I paid $171 for 100' of LMR400 the same crimp kit on dxengineering and 4 pl259 connector with tax. 100' was 69.00, about $.20 cheaper then I could find anywhere else and is LMR400 equivalant spec'ed.

  11. Still tweaking it but very close to the last photo. Almost all the text is grey, except on the right side. Mostly because it was limited by what eqsl.cc would let me do.
  12. Around the 9-10 minute mark you will hear the Roger beep the a burst of static. The burst is the repeater tail. Closing the connection. Sent from my SM-G975U using Tapatalk
  13. No. But I have heard some repeaters send identifiers at the end of someone's transmission. Sent from my SM-G975U using Tapatalk
  14. Would sound like a second or two of static. Then quiet. Sometimes a beep if the repeater is setup with a Roger beep. No repeater tail, then you aren't breaking the repeater squelch, making it into the repeater or have the wrong tone Sent from my SM-G975U using Tapatalk
  15. Did you hear a repeater tail after your transmission? Sent from my SM-G975U using Tapatalk
  16. Frankly, for an ammo can repeater. I probably would do a roll up jpole with some coax. Get some fishing sinkers and 50lb test (or heavy) mono filament. Tie the sinker to the line, and huck it over a tree branch. Even better if you have a sling shot and are decent shot. Then tie the roll up jpole, attach the coax to the line and pull upwards. Till you can't get it higher or run out of coax. Really starting to like RG400 over LMR400 for some of the runs I am doing. But can be pretty lossy in 100 lengths. Plus you really don't need the Teflon isolator in GMRS. Nut OMG how flexible RG400 is over LMR400. But with that setup you can get the antenna up higher. Giving you better LOS and range. If you decide to add solar it will also give you some more isolation from the antenna, as long as RFI isn't making it in by the radio and power lines.
  17. Instead of cutting. Contact larsen to see of you can get a po-450 whip. Should be about $10. Po450 is their gmrs 5/8th model tuned for 450-470. The bases and parts on larsens models are mostly interchangeable. If you are super impatient then find some steel stock rod from the hardware store about the same thickness. You'll be targeting a length around 1.25 range then adjust from there. The 2/70 is a collinear design. So tuning them is a no no. You usually screw it up more then anything for the 70cm service you basically have two stacked antennas with the coil being the separator. If you start trimming you may end up with phasing issues or even worse erratic and weird vswr numbers and curves.. Sent from my SM-G975U using Tapatalk
  18. I would do 3. But I have the tools to do it. The losses from the connectors isn't going to be huge. Or Personally if I was feeling lazy. I would patch repair it, if everything checked out. I would fill the cut ( I imagine a cut) with silicone all-weather adhesive (gasket former) style rtv. Then over wrap 2x with self almagating tape. Going several inches past the wound on both sides. Then a final 1/4 stretched wrap with a uv stablized electrical tape. We always used 88t when we where doing telephone work. Got yelled at a lot by the bosses for calling it electrical tape.

  19. I like that setup. Sent from my SM-G975U using Tapatalk
  20. Intesting read... would of thought there would have been more picket fencing from multi pathing. But it seams you basically are going to get crystal clear or nada due to phasing. Sent from my SM-G975U using Tapatalk
  21. That is the thing with propagation studies. You can get reflections, knife edge propagation, localized ducting. Any number of things could have occurred. Which make it better or worse. Funny enough even the type of foliage can aid or hinder propagation. Have you headed back up there since? Was the weather different? Sent from my SM-G975U using Tapatalk
  22. Suppose to be good for 160-6m. With a wide band tuner. I have an ltg 100 pro ii. We shall see. Since it is really for listening so should work well for that. Really wanted something permanent for NVIS and ground wave on 10/6. The photo was from a walk my wife took behind the house with the kids. She said IRL it looks just like a birdhird feeder and the wires are unnoticeable. Working on a fan dipole for 40/20/15/10/6. Just need to set it up to tune.. That will be stop gap till I get the general ticket. Then the next step will be either the Dx commander or nebula for DX work. Sent from my SM-G975U using Tapatalk
  23. Finally, got my Ultimax DX Extreme 72' Random Wire Antenna up. Mounted the transformer/unun to the bottom of a bird feeder with RG58 and counterpoise wire down bird feeder pole. In a vain attempt to hide it a bit from the HOA. The other end is tied to 50Lb Mono filament that I was fortunate to hook around the LNB of a satellite dish mounted to the chimney. This took several attempts, one attempt resulted in a cut monofilament when I hooked the angle adjuster. One attempt nearly end my day as I started to slide off the roof. Resulting in a lot of pulled muscles, burns from the hot shingles. *** it was a lot steeper then I thought originally. I do not recommend climbing the roof. Hire someone. The RG58 runs down the pole, I have yet to trench the RG213 from the DX Engineering NEMEA box which I had finally got installed and grounded the previous weekend. Sadly, now waiting on RG400 for the patch lines into the shack. Now I am contemplating switching from LMR400 to RG400 for the feed line to the 2m/70cm antenna in the attic. The bird feeder antenna in all it's glory. Photo is before the antenna was pulled and counterpoise was buried.
  24. Done that. It is a test mode, locked to a frequency that you set before you power down to get into the test mode. So more of a kludge then a hack.
  25. Yup, that is what amateur radio is about. I figured SSB on 70cm isn't all that popular due to range, unless you get lucky with tropo. So much I have dropped 70cm SSB from my plans. Even 2m SSB maybe dropped. Sent from my SM-G975U using Tapatalk
