QUOTE(wiraone @ Aug 28 2014, 11:31 AM) Insulator? Just about anything that can isolate the wires. Some people use chopping board, cut and drill holes, some people just used wood. Buy 3M stretchable tape, you can get it from any electrical shop to water proof the connector or else, water can seep through your 50ohm cable (RG58, you can get it from Jalan Pasar for RM6-8/meter). 2 elements for 3 bands wasn't good enough. that's why we only got 1068 contacts. we need 6 elements for single band. sifu wiraone, please help me build one.Join one of the field-day activities and you can see/ask what they're using for their antennas. During our last outing at Sri Iskandar, we had a big A4S yagi antenna, but we couldn't tune it to anything other than for 10M, so, we decided to go with EFHW (End fed half wave) a simple wire with a tuner and we got a pile-up. For my last IOTA outing with Piju, we used a two element yagi and it was a good setup too. This post has been edited by piju: Sep 8 2014, 04:35 PM |

does anyone here used a china baofeng lineup handy for Rx only iGate before.im hesitate to try because some say the Rx delay is awfull and the beacon will not fully be decoded/half received.

No idea about Baofeng, but some China made handies are as you said, slow in opening the squelch and causes problem in decoding the signal. What you can do to minimise them is to turn off any power saving features on the handies. I do know that 9W2SVT is using China made handy for his setup. So, not all having this problem. |

More info on Baofeng problem's with packet:
http://illruminations.com/2014/01/15/baofe...dio-adventures/ But, toward the end, there seems to be a solution given. http://larr-project.blogspot.com/2014/01/e...-detect-in.html Good luck! |

Wait until you guys really hooked into working DX on HF, you'll forgotten what expensive mean to you. Haha.. it is just like playing golf

Haha.. it is just like playing golf I am going to do some antenna by using existing astro RG6 coax and with some connector , found out that I need to get SMA Male Plug to F Female RF Coax Coaxial Connector, but question, is the RG6 so call 50 Ohm? I am testing to do some G5RV, because the receiving for my exisiting long wire antenna around my first and second room is not so "good", even if only receiving... |

RG6 is a 75 Ohm, RG58 is the cheapest 50 Ohm feedline. RG58 is the same as the network 10-baseT coax cable we had ages ago to interconnect our PC, now can only be seen in certain shops. You can buy it from One Comms too, no idea how much per meter now though. |

I'm not good in antenna design, wait for piju to come in and explain all about the feedline and the impedance and on how you should feed your radio. Our radios are normally feed by a 50Ohm coax feedline, so if you're using a 75Ohm feedline for transmitting, you'll have a mismatch and your power going out will get lost. Receiving should be okay though.I wanna try do it as maybe next time I may use to transmit Read more about the feedline here: http://www.arrl.org/feed-lines http://www.jpole-antenna.com/2013/01/12/wh...for-my-antenna/ This post has been edited by wiraone: Sep 10 2014, 10:51 AM |
