Yeah the antenna was quite a project. When the spec was to have a rigid HF antenna and mast collapse to 18" or less I realized commercial products wouldn't cut it. It was time consuming to source lightweight materials and modify them to suit but it worked out well in the end. I hope a commercial manufacturer makes this stuff someday as its sure a lot easier to buy it than build it. |

I wonder what the battery pack in the baby wipe box looks like when it is screened at the airport? A friend of mine is an instructor and travels a lot. He has one of those pads you use to write on for use with a laptop and projector. I guess it looks pretty wild on their scanners. He never had a problem until he went to Wyoming. They freaked and he missed his flight. He hasn't had a problem since. I like the setup. The fact that you made it is even better. Vince. |

With my FT-817, I use RC car battery packs. I've been though both TSA and Customs with them; I do them a favor and put the radio and battery in a seperate tub so it doesn't look goofy on the CTX machines which show density of objects. |

Quote: Minimum of 20W, preferable to have optional 50W+ available if needed OSHA would cringe! Love that battery!! I once cleared out the Port Townsend police department when I found a "device" in a bike style water bottle that turned out to be a (probably commercially available :roll: ) bike light battery... Oh the memories... :mrgreen: |

Another problem is that it doesn't do 60/80 meters. The biggest problem is that they didn't seem to have time to respond to emails with product questions. I responded in kind by not finding time to purchase their products. I looked at Super Antenna however I did not see any size/weight specifications on their website. This is kind of silly when they are selling products claiming to be portable. Their website doesn't specify what kind of whip they use however I doubt it is an 8-foot collapsible which is what I prefer. Their antenna is only good to 40 meters and appears to use an additional long non-tappable coil for 80 meters. This creates two problems as there is no place to tap for 60 meters and their coil design might not fit in the pack. Like I said, commercial products didn't cut it. |
