I am back in the forest and continue to experiment with Ham Radio antennas / portable. Today I find out which dipole is better, vertical or horizontal.
What is your experience?

I was told during the courses that it wouldn't matter because the atmosphere scrambles the polarization for HF. It's great to see the experimental results confirming it. Thank you very much.

The only real effect from the orientation would be the signal lobes. Horizontal will be more directional - perpendicular to the direction of the elements. Vertical will be more omnidirectional.

I had the same results on 20M during the day (Indiana, USA), but at night the horizontal position seems to work better on the broadside directions, while the end directions seem to stay the same. Next, I'm going to try out vertical with radials (like the DX Commander) and compare it to a vertical dipole. Keep up the great work!

Any radials are better then no radials, something I have not tried with a dipole myself, but i orobabky will now you mentioned it. I have 10 x 7m radials on a board but 3/4 is suffice if any at all, I also have a 40+m a long counterpoise, not that it's needed I just like to experiment with antennas I have created myself, and I am far from a Tech or Ham Expert, more The Experimental Ham Guy. 73's Ed

Hello Raisa, at first thank you so much for your contribution to the ham spirit and compliments for your videos and acitivity.About this video, to measure the horizontal to vertical attenuation, you should use a calibrated test receiver or a spectrum analyzer, a CW stable source and than a anechoic chamber or a reflection free area: in this case you will see really the difference, I did it. Depending of the balun, closed or open dipole, diameter of the radiator, could be 6 to 12 dB, 1 to 2 S points.On wikipedia there are more details. We made in the past a logged QSO. Thank you again and encourage you to continue in your activity to improve ham world. Greetings 88 , Sandro IW1FQC

При низком диполе радиоволны в большей мере поглощаются землёй,но это всё зависит от состава почвы и её влажности.Поэтому,иногда,вертикальный штырь бывает во много раз эффективнее - всё зависит от состава почвы,её влажности и что в данное время происходит в ионосфере,а также различных препятствий радиоволн.Поэтому всегда всё относительно.

That was a great comparison of 2 dipoles. I am in the USA , we love them DX Commander mast. saving money to get the new 2024 DC Commander expedition portable antenna. he now has clamps to keep mast from collapsing down on it self. 6 threw 40 meters . going to cut extra elements for 3/4 wave 11 meter. 10 and 12 as well and a 3/4 wave 6 meter one. with the higher frequency you can cut 3/4 wave and wont be so long and still tune 50 ohm. I hade good luck in a park on 6 meters off set center dipole. tree to tree. 3/4 on center/1/4 in shield. match 1.5 or less threw the whole band. lately 6 meters not so good local only/ springtime has some nice DX . 73's

Does the antenna switch switch switch the shield of the coax as well as the center conductor? If not the horizontal dipole has a third wire which is vertical and the vertical dipole has a third wire that is horizontal. If the two coax feedline braids are connected then it will not show the real difference in the antennas. You could put a double pole double throw switch in a box and connect the feedlines so that the shield of the vertical dipole and the shield of the horizontal dipole are not connected together. Then the results should be different. Basically your vertical is not completely vertical and your horizontal is not completely horizontal!

On one of the forums I found a good answer for you, which gave Kevin Reid AG6YO "For VHF, choice of polarization is not up to your desired radiation pattern, but who you want to be able to communicate with. In HF, the ionosphere causes random rotation of your signal's polarization, but in all line-of-sight communication, VHF or higher, there is no such rotation and a polarization mismatch can result in no signal at all. You should use vertical polarization if you wish to communicate with existing FM mobile and repeater stations, because they also use vertically polarized antennas (by convention, and because quarter-wave verticals are much more convenient than other types of antennas on vehicles and handhelds). On the other hand, you should use horizontal polarization if you are attempting 2 meter SSB or other types of DX/weak-signal work. Again by convention, but the convention arises because (if I understand correctly) horizontal dipoles typically have more gain, and because a horizontal dipole is a simple, efficient freestanding antenna. If you wish to be able to communicate with both types of stations using a single antenna, you can use a diagonally or circularly polarized antenna, as a compromise which has a reliable small amount of loss in either case. However, such antennas are more directional than a vertical (at least as much as a horizontal dipole) and thus require pointing." Thanks Kevin! de R1BIG

ДАВАЙТЕ Я ЕЩЁ РАЗ ОБЪЯСНЮ ПРО АНТЕННЫ: Всё всегда относительно: Чем ближе диполь находится к земле,тем больше радиоволн поглощает земля,если эта земля плодородная(чернозём)и влажная;если эта земля глинистая и сухая,то эта земля будет отражать от себя радиоволны. Если на пути распространения радиоволн находится много препятствий,то более эффективной антенной в этом случае будет диполь,но если на пути радиоволн нет препятствий в виде высоких гор или бетонных зданий,то лучшей антенной будет вертикальный штырь,и чем выше будет поднят этот штырь,тем лучше для связи как на ближние расстояния,так и на дальние - всё относительно,так как состав почвы и её влажность играют очень большую роль. Не менее важной особенностью радиосвязи,особенно дальней,играют изменения солнечной активности в ионосфере в разные часы суток и погоды. Поэтому,после дождя всегда для наиболее эффективной связи будет антенна из вертикального штыря,если в этом случае нет препятствий для радиоволн в виде высоко этажных зданий или высоких гор.Если эти препятствия(здания и горы)для радиоволн присутствуют и почва сухая,то наиболее эффективной антенной будет диполь или,лучше,волновой канал. ВСЁ ВСЕГДА ОТНОСИТЕЛЬНО.

I live beside the coast, I find signals (DX) much more enhanced over the sea. I work Australia with only 10W ssb and a loaded 1.4m whip antenna. I wondered if it would be same for you, but over lake water,.. 73 de G4FBC

Отличное видео, спасибо, как бальзам на душу... А можно как-то повторить, чтобы провести WSPR тесты и сравнить их результаты?

Владимир, не обещаю. В лесу уже много комаров развелось. А такой тест требует длительной технической подготовки. Но в ближайшее время продолжу некоторые другие необычные эксперименты с антеннами на природе ;-)

@@YLRaisa Спасибо за ответ. Да, согласен про подготовку, но все настройки ноутбука+трансивера можно, и даже нужно и удобнее, провести в стационарных условиях, на примере наличных антенн. В крайнем случае можно при настройке делать анализ одной и той же антенны, но на разных диапазонах. А за тем по отлаженному алгоритму повторить в полевых условиях, сами замеры займут несколько минут. Да комары умеют доставлять неудобства... Но даже и для одной антенны результат WSPR теста могут быть интересны и полезны.

Тут еще такой момент, в этом переключателе у тебя при переключении второй порт все равно подключен через емкость разомкнутого контакта. Т.е. ослабление конечно есть, но около 20-30дб (можно померять точней). Так что эксперимент не совсем чистый 😉 Я улучшал развязку между портами если отключенный порт подключается на нагрузку. Но лучше 30-35дб развязать не получается. 73!

Олег, ты, конечно, прав. Наша переключалка (made by RA1AMO) тоже вносит свою лепту. А вот у меня есть старый Кенвуд, там два гнезда антенных, можно сразу 2 антенны вставить в него. Так будет более чистый эксперимент или это тоже самое?

@@YLRaisa я думаю так будет более честно. Можно посмотреть какая там изоляция между входами. Подключить сигнал к 1 входу, а слушать на 2. А вообще как тут уже писали на КВ поляризация не так сильно влияет. Где-то слышал что в пределах 3дб всего, это полбалла по S-метру.

Raisa, you should try sometime on your rigs that support receive antennas using a vertical and horizontal at the same time. I have heard myself the reduction in fading on the band as a signal goes from horizontal to vertical. This is one of the ways of doing diversity receive. Thanks for the video.

@@sergioborghesan6318 No you can use 2 antennas, one in each ear and hear it. Phasing is a completely different type of diversity. Phasing requires processing in a device to phase the signals and diff them. My Apache Labs Anan has phasing where as the Flexradio I have will do the fading as long as I have both a horizontal and vertical antenna tied in. Also realize I am not talking about transmitting. This is receiving.
