I then changed to a 1/4-wave whip and worked him first call. I attributed this to the fact that with a 5/8 the major lobe is towards the horizon whereas a 1/4-wave has a lobe tilted further upwards.\n\nRegards,\nKeith G0RQQ\n\n\nSent from my BlackBerry 10 smartphone on the O2 network.\n Original Message \nFrom: John Geiger\nSent: Saturday, 30 June 2018 16:44\nTo: David Quick\nCc: AMSAT\nSubject: Re: [amsat-bb] AO91, AO92 and XW-2 sats with mobile whips\n\nHi Dave,\n\nThat is great to know. Sounds like it would work. I wonder if a 1/4 wave\nantenna might be better than a 5/8 wave as it might have some higher lobes\nas well and cover more of the pass. Does anyone know about this?\n\n73 John AF5CC\n\nOn Fri, Jun 29, 2018 at 8:20 PM, David Quick <[email protected]>\nwrote:\n\n> I have made numerous AO-85, 91, 92, and SO-50 contacts from my truck,\n> mostly\n> while stationary due to the desire to log the contacts, with a 25 year old\n> Kenwood TM-733a (~25 watts) and a dual-band antenna on the roof of the\n> truck.
