RS Whip
|
Whilst at local Radio Shack, I picked up a telescoping whip antenna
which extends to 72" for <$5. Thinking of adding either a BNC or PL- 259 connector to the end. With a counterpoise, it should work on 6m. Certainly better than the rubber dummy load that ships with the 817. Anybody tried this? With a BNC connector on the end, I should be able to plug it right into the jack on my ZM-2 tuner and end-feed it at a 6' whip. With suitable counterpoise it should "work" on other bands. I wonder how it will compare with the ATX and PM-1 (or is it MP-1, I can never remember). I have Verne's last year model which works OK. It's a bit fatter than the new one, and just as contankerous to tune without a meter, but it does work. For serious QRP portable workings, I take a 33' fiberglass mast on which I hang assorted dipoles, deltas, and vertical wires. But occasionally, I don't want to carry all that gear and just want something small and light, which makes ATX and Maldol attractive, but I hate the price. Does anybody know where I can buy helium in a small spray can? A couple of small baloons ought to hold up a decent length of wire for an hour or two of operating. I thought about flying a kite (have been told to do that before), but had a horrible mental image of me chasing my 817 as a gust of wind drags it/me away... This is a fun radio and a fun list. |

John,
I constructed the RS back of set antenna as seen in the files section. I made a small wire-ring jumper for bypassing the coil and with the bottom two sections out and the top section 2/3 rds out (I think). It came up perfect on 50.125. Having said that I have not worked any stations with it yet. Alternatively, I am waiting for my mounting bracket from superantennas and I intend to use a 3/8" whip tip adapter drilled out to accept the banana plug of the above set. Then I should be good to go with on 6 and 2 side band. Btw, I have already made up a wire for counterpoise use, but didn't need it today. I can't wait to get in the mount bracket and start trying out all sorts of other antennas. 72/73, Bryan ¨C k0emt |

Sam's Club ( a wholesale-type warehouse store ) or any party supply place sells balloon kits with a 20lb-type can of helium and some balloons. This is a fun radio and a fun list. Even with our clothes on... Thanks Pres Waterman W2PW c/o Patchogue Motors, Inc. Long Island Ford and Kia dealer GO BILLS! |

Stick with the fiberglass mast because I have an even more horribleCheck out New Jersey QRP Club's website for a great article on making & using kites for antenna supports. It should be applicable to balloons as well. The relevant point: use MUCH lower strength line from your antenna connection point to the kite than you use from the antenna down to the ground. If you lose control of the kite, the line will break at the connection point, and the antenna will fall straight down. Of course, you would ANCHOR the line at the ground in order for this to work, so it would be impossible to drag your rig off, anyway. <snip completely unneccessary comment, and signature line> Folks have used kites & baloons for all sorts of stuff for centuries (remember the Montgofier brothers? 1873 first manned balloon flight) It obviously *can* be done safely. But also, folks die every year from doing it *not* so safely, so use yer noggin! I have no connection w/NJQRP yadda yadda.... |

Where do you get a 33' figerglass mast? I assume it telescopes?

Don
For a 33' mast try the MFJ-1910.
