Bruce It would be better to make it "non-resonant" (about 210 ft) and avoid the sky-high impedence that a 160m half-wave dipole would present on even multiples of that frequency, i.e. 80m, 40m, 20m, 10m. Ladder- line is good, especially at the higher frequencies. Please note that the radiation pattern may not have much broadside power when the antenna is more than one-wavelength long and mounted more than one- quarter-wavelength high. An antenna analysis program like ELNEC will give you an *estimate* of the radiation pattern and impedences. Dunno what "half way decent performance" really means. A lot of Hams swear by their 105' centerfed with ladder-line... how does 10dbi gain at a take-off-angle of 16 degrees sound on 10m? Not nearly as good as a 5 element Quad... but for $30 it works. 73, Cecil, kg7bk@indirect.com ------------------------------ Date: Fri, 14 Jan 1994 18:32:04 GMT From: netcomsv!netcom.com!greg@decwrl.dec.com Subject: DIPOLES FED BY LADDER LINE To: info-hams@ucsd.edu In article k1zat@bah.COM (J.

It's quite old (10-15 yrs) and are becoming a bit - well, *used* if you know what I mean. It covers 10 through 20m. Gain ca 9dB - not so very impressive, but the F/B ratio is very good (cant remember actual number). The TH7 and TH11 will outperform it by far, apart from the continous coverage. It's nice to have *one* antenna to work all the bands including WARC. The good F/B ratio is useful on the lower bands , as a recieve-ant. For our purposes (limited space), the Log is a nice compromise to work DX, and it really works. Espen LA6MGA/LA1K, DoD# 7962 Disclaimer????

Windows Ham Radio CDROM Well, we've finally finished it and there are a bunch of new features. First off, in addition to the DOS search program, we now have a Microsoft Windows compatible search engine which adds tons of new functionality. We now support searches by callsign, name, city, zip code, street address, and previous callsign. The Canadian callsigns are also integrated right into the main database. The windows software allows printing on any Windows installed printer and provides for editing of search results files - using any editor you choose. We've also added a new section containing prerecorded RTTY, AMTOR, ASCII, and Packet messages for TNC testing. These .WAV files are SoundBlaster compatible and come in all popular speeds and shifts. We've also taken the mods database and placed it into hypertext format which means that you can browse it using only the mouse under windows. All of the popular text files from buffalo.edu are also hyper-ized. In addition, we've included the last 10 months of the rec.radio.* newsgroup articles, along with the usual large batch of shareware. We have also committed to a quarterly updating schedule which will mean a new disc every 3 months with the latest FCC data. As before, we're making a special offer to readers of the rec.radio newsgroups. To find out how to get your first edition copy of QRZ! Windows direct from the author, send an e-mail message to: info@qrz.com You'll receive an automatic reply with ordering info.

It's Sunday the 16th of January and here is the GB2RS news broadcast, prepared by the Radio Society of Great Britain. First the headlines:- Another RSGB member has received an honour; science teachers are to promote amateur radio in schools and Estonia has signed the CEPT 'instant reciprocal licence' agreement. Congratulations to RSGB member Donald Alexander Michael, GM0KCY who received an MBE in the 1994 New Year Honours list in recognition of his work with the Lighthouse Service, the Northern Lighthouse Board which looks after the Lighthouses of Scotland and the Isle of Man. Donald is Principle Lightkeeper at Cosewall Lighthouse, the last manned light on the Rhins Peninsula, but will be moving in March when Cosewell is converted to an automatic unmanned station. His next assignment will be on the Isle of Lewis, Outer Hebrides, IOTA reference number EU10. At the recent Annual Meeting of the Association for Science Education at Birmingham University an organisation known as STELAR was formed. STELAR, Science and Technology through Educational Links with Amateur Radio, is a group of educationalists whose aim is to promote amateur radio as a means of supporting good practice in the teaching of science and technology. Further details will be published in the February edition of Radio Communication, or anyone interested can contact STELAR's Chairman Richard Horton, G3XWH, whose address is correct in the RSGB Call Book. The Radiocommunications Agency has informed the Society that the government of the Republic of Estonia has signed the CEPT T/R 61-01 agreement. This means that a reciprocal licence is no longer required for UK amateurs to operate in Estonia and vice versa. The letters ES followed by a number from zero to 8 indicating the administrative district, will be used by visiting amateur. Now some items of HF DX news from the weekly RSGB DX News Sheet which is edited by Brendan McCartney, G4DYO. From Montserrat, K8SJ will sign VP2MFA from now until Thursday the 27th of January. He will operate on all bands from 1.8 to 28MHz, CW. Full details of his operating schedule can be found in the RSGB DX News Sheet. From the Falkland Islands, the 'Peter First Team' will operate as VP8BZL from yesterday, Saturday the 15th until Sunday the 23rd of January, with emphasis on the WARC and LF Bands. From Croatia, K4XU will sign 9A/K4XU from now until March using CW. Check these two frequencies, 7.025 or 14.025MHz from 1800 - 0200 UTC daily. And from Reunion Island, JE8XRF will be active as FR/JE8XRF during Tuesday the 18th and Wednesday the 19th of January. Activity will be on the 10 - 80 metre bands, mainly on SSB with some CW operation. We have no rally news for you this week and there is only one rally that we know for next Sunday the 23rd of January: The Oldham Amateur Radio Club Radio Rally which is to be held at the Queen Elizabeth Hall, Civic Centre, West Street, Oldham, Lancs. Doors open at 11.00am, or 10.30 for disabled visitors. The rally features many trade stands and a bring and buy stall. Refreshments will be available from 11.30am. Talk-in will be on channel S22 via GB4ORC starting at 7.30am. Further details can be obtained from Kathy, G4ZEP on 061 652 8617 (evening) or 061 633 0550 (day). HF contest news now: RSGB LF Cumulative 7.0MHz Contests take place today Sunday the 16th and next Sunday the 23rd of January. They run from 1000 - 1200 UTC. RSGB LF Cumulative 3.5MHz Contests take place today and next Saturday the 22nd. Both are from 1600 - 1800 UTC. An RSGB LF Cumulative 1.8MHz Contest takes place next Wednesday the 19th of January from 2000 - 2200UTC. December's RadCom, page 84, gives detailed information on all of these LF Cumulative Contests. Next some VHF contest news: The RSGB 144MHz CW Single Operator Fixed and All Others Contest takes place today, Sunday the 16th, from 1000 to 1600 UTC. There are three sections:- Fixed station single operator, Open and Listeners. The first RSGB 70MHz Cumulatives Contest takes place next Sunday the 23rd of January from 1000 - 1200 UTC. See December's RadCom for details for both the VHF events. And now the solar factual data: The period from the 27th of December to the 9th of January has seen a considerable number of M flares, on an almost daily basis from the 27th of December through to the 5th of January. The biggest flares were an M6.5/SN on the 2nd of January and an M6.0/SN on the 3rd of January. Sunspot indices have increased considerably and meaned at 125 for the period, though the 4th of January was up to 170. Solar flux levels have also increased considerably and averaged 132 units, with the 1st of January being up to 148 units, the highest daily level since February 1993. There have been a number of SIDs, sudden ionospheric disturbances, but most did not last long. The geomagnetic Ap indices have been mainly quiet, except for the period from the 31st of December to the 3rd of January which was disturbed due to the flare activity. The period averaged an Ap index of 10 units, with the very quiet periods being around 3 to 5 units. The state has been 'nil', except for the stratwarm which is continuing and now covers Southern Europe as well. The radio quality indices rose to very high levels and were up to 'excellent' by the 31st of December. The aa indices for the 28th of December to the 3rd of January were very quiet up to the 30th, then became just unsettled with the daily indices averaging 23.2 nanoTeslas about K3. The X-Ray flux has risen to the highest weekly levels since February 1993. The 31st of December was up to B8.9 units, the highest daily level since the 1st of March 1993. The period averaged B4.3 units. The monthly mean sunspot index for December was RI 49.4, with the maximum being 99 on the 31st and the minimum being 8 on the 15th. The smoothed index for June 1993 was 55.9 plus or minus 5. Now the ionospheric data for Central France: The F2 daytime critical frequencies at Poitiers, as reported by Meudon, averaged 8.2MHz, but were up to 11.5MHz on the 31st, the highest level since January 93. The darkness hour lows averaged 3.2MHz and did not change much from day to day. Now the ionospheric data for the north: The F2 daytime critical frequencies at Ekaterinberg averaged 7.4MHz, but the 5th was up to 8.9MHz, a very high level for this observatory. The darkness hour lows averaged 2.4MHz, though levels ranged day to day from 1.8MHz up to 3.5MHz. Though we have not been informed officially, we understand that the Darmstadt ionospheric observatory closed down on the 31st of December; it means that the radio quality indices will no longer be available. This is just one more indication of the declining commercial interest in the ionosphere. And lastly the solar forecast: This week, the quiet side of the sun will be rotating away. The big increase in solar activity is unlikely to be evident this week as it is confined more to the active side. Solar flux levels are expected to be around the 100. The geomagnetic activity is expected to be mainly quiet or just unsettled. The radio quality levels, based on past performance, are expected to be normal or just above. And that's the end of the solar information. Finally in the main news, SSL has informed the Society that as of last Wednesday morning, the latest callsigns issued were in the G0 U I and G7 R N series, and Novice calls in the 2 0 A H and 2 1 C M series. You're listening to GB2RS, the news broadcasting service of the Radio Society of Great Britain, transmitting in the 80, 40, 6 and 2 metre bands. Next, the local news.
