My antennae Here are the antennas I use at the moment. See also under the remotestation tab. At the bottom of the page there are also some tips and links for those of you who like to build your own antennas. The beam is a Hygain Explorer and it has the bands 30m, 20m, 15m and 10m. Above it a warcbands dipole and at the top a vertical from Diamond for 2m and 70cm. It's all mounted on a sled so I can lower the antennas to the top for easier servicing. Here is the rotor that I turn the antennas with. It sits on the floor in the attic and I built it from a Permobil engine, two gearboxes and chain drive. The rotor is operated with a control box from CDE. I use this antenna for the 40m and 80m bands. The upper part for 80m is slightly shortened and thus adapted for the attachment points I have access to but performance and bandwidth is basically equivalent to a full length dipole. The coils inductance is 30 Mikrohenry, read more about the coils further down the page. Antenna analysis 80m Antenna analysis 40m Here is a picture of my 80m vertical that I have mounted on my boathouse. The antenna has a coil in the middle and uses the tin roof of the boat house as a ground plane. If you don't have access to the metal roof or the like, it works just as well with counterweight ropes. Antennas for smaller gardens Shortened antenna for the 80m band that works well. This antenna is much shorter and thus narrower, but works to tune with the radio's internal tuner over the entire band with good results. The coils are of the same construction as on my wire antenna for 80m and 40m further up the side. They are wound on 50 mm electrician's pipe. By wrapping with RK el. FK1.5mm2 automatically gets a "pitch" of 1:2. 45 turns gives the desired 30uH. A 140 mm pipe length is used for the winding itself, but a 160 mm pipe is used to accommodate the reliefs. The antenna is previously posted by SM4FPD, thanks Roy for a good antenna for small spaces. Really good Windom antenna for all bands from 40m to 10m including the Warc bands. Works very well and goes on all bands including the warc bands without too high SWR. Can be tuned with good results on 6m but works poorly on 80m. Avoid running the coax parallel to the antenna wires and preferably use a - RF-choke or similar to prevent RF to the shack, which can be a problem with Windom antennas. I myself have some tube ferrites on the coax just below the balun and have never noticed any RF in the shack. I bought this antenna but it is easy to build yourself. The antenna is designed and sold by Nigel Booth - M0CVO This is another good multiband antenna with small dimensions that also works well even on 80m.

Troligen Sveriges dyraste stege då min dotter som monterade ihop den fick 4 kronor för varje stegpinne :-) Här kan man se de låga förlusterna vid en stegmatad antenn. Kan man bara stämma av den så är furlusterna försvinnade små. Längkarta på dipol och steglängder En linkkopplad Anneke-tuner avsedd för stegmatning. Vill man slippa tuner går det bra att koppla in olika steglängder för att hamna rätt. Baluns and chokes Here, 2 baluns are suitable for several of the antennas on the side. They are wound on the toroid core Amidon FT 240-43 which is easy to find for purchase._cc781905-5cde-3194-bb3b-136bad5cf5 50d_Maxw power ca. If you need higher power endurance, you stack two cores, maximum power 1000w. If you want to read more about baluns and how you make them, visit Wolfgang Wippermann's (SK) website. He was a guru on baluns and on the website he shares the knowledge of building well-functioning baluns. https://www.wolfgang-wippermann.de/ Här på VK6YSF hemsida hittar du också bra beskrivningar hur du bygger baluner. https://vk6ysf.com/balun_choke_balun_low_vhf.htm You can build an RF choke by wrapping the coax around a plastic tube, a so-called "uggly balun". The coax wound around a toroid core provides a wider bandwidth RF-Choke. You can see the number of turns and frame/toroid here. Antennmyter inom amatörradion Bertil Lindqvist, SM6ENG, har funderat mycket över myterna inom amatörradiovärlden. Här har han sammanställt och kommenterat ett antal av de myter och missförstånd han tycker är vanligast förekommande. Även Bengt Lundgren, SM6APQ (Silent key) är med som författare. Sidorna är hämtade från ESR med deras godkännande. Besök gärna deras hemsida som innehåller mycket matnyttigt för den teknikintresserade amatören. - Måste en antenn vara i resonans för att fungera? - Tar en antennanpassningsenhet bort ståendevåg på koaxialkabeln? - Missförstånd om kabelns karateristiska impedans - Ger en koaxialkabel med hög förlust upphov till ståendevåg? - Fungerar en öppen feeder som en antenn? - En lågt sittande dipol har ingen riktverkan - Är G5RV en multibandantenn? - Förlorar man lika mycket i sändning som i mottagning om verkningsgraden i en antenn är dålig? - Ger högt ståendevågförhållande RF-Problem (EMI) för närliggande utrustningar? - Om vi har en sändare som ger 100W uteffekt och ståendevågförhållandet (SVF) är 3:1 kommer det då ut 75W i antennen? - Det finns motsägande budskap om baluner - Hur påverkas ståendevågförhållandet av PL-259-kontakten? - Jordning - Myter om balanserade/obalanserade koaxialkablar och antenner - "Tysta antenner" - Balanserad matning och feederstrålning - Horisontella dipoler över reel jord - Koaxdipoler Links Here are some useful links for those of you building antennas K7MEM M0UKD 1728.0rg Lots of wire antennas Antenna simulation program DK7ZB:s hemsida med massor av antennritningar IZ0UPS Workshop (Italienska)

QRolle Here are some pictures and information about the QRolle Classic that I built. QRolle Classic is a QRP station for SSB on the bands 20m and 80m. It can also be easily further developed for CW traffic. OROlle is designed by SM6DJH Olof Holmstrand. All construction information is available on the internet, so it is still possible to build your own QRolle. The page where all the information is available is http://qrolle.thulesius.se/ Visit the page and be inspired to build your own QRolle.

In order for our hobby to be as pleasant as possible, it might be a good idea to adhere to some rules about how to behave on the bands. A radio amateur must be tolerant. We share frequencies with many other people, some of whom will not have the same opinion as you. We don't talk derogatorily about people. Be mindful of what you say and avoid discussing topics that may seem upsetting or offensive. Topics that should be avoided are religion and outlook, political ideology, or economic social issues etc. where opposing parties may have strong opinions which do not necessarily match your own. We completely avoid profanity, sex words and the like. Understand that everyone may not have the same skills, experience and more. Act humbly towards other people on the bands. If you or someone else gets upset, avoid acting on it, instead behave like an adult in such situations and try to calm the situation down. Stations that deliberately interfere are ignored, attention usually only makes the problem worse. L call before sending and ask if the sequence is available if you are unsure. Also listen a few khz above and below the frequency you intend to use so you don't disturb ongoing traffic near your frequency. Call correctly and exit correctly. A matörradion is mainly for technical discussions of a purely private nature or of general interest for the hobby, tests and exams and more. Approach to DX traffic I listening and listening and listening again before calling the DX station. I calling The DX station only if I can perceive the DX station properly. I don't trust the DX cluster but be sure of the DX station's callsign before I do calling The DX station. I do not disturb the DX station or anyone who calling The DX station and I never transmit on the DX station frequency vid split-QSO I waiting for the DX station to finish a contact before I calling . I always enter my entire signal. I does not call DX station continuously. After calling the DX station, I listen carefully. I calling not when the DX operator answers another call sign, not mine. I answers or calling not when the DX operator asks for a signal that is not mine. I calling not when the DX station is requesting geographic areas other than mine Are there more stations waiting to finishI my QSO with the DX station as soon as we exchange the necessary information unless the DX station expressly wants to conduct a longer QSO with me.
