Could you please advise on how senior management can improve communication and connectivity?

目前手台使用的天线是老鹰775，需要在窗边才能收到中继信号，发射时需要打开窗户，冬天感觉有点难顶。问了几位群里的HAM，推荐买吸盘天线固定在窗外的空调外机上。
但我这一侧的窗户够不到空调外机，只有窗户外边大约10厘米的一个窗沿可以固定，求问各位 HAM 这种情况该怎样改进通联条件？是买吸盘天线直接粘到外面的窗沿上，还是买玻璃钢天线架在室内，或者有其他更好的方案吗？
感谢各位指教。

BI1SCY Attach a support to the window sill, extending it for a short distance.

BI1SCY Or, invest more time in learning about and using a single platform for all aspects of radio operation, such as MMDVM, which allows you to work with both analog and digital signals, including VHF, shortwave, Morse code, and even building your own antennas.

BI1SCY 那就买跟够长的线接上不就完事了

BH8UTF The window sill is a platform, and I'm having trouble figuring out how to fix it securely. I originally planned to buy suction cup antennas and use nano-adhesive to attach them.

YofoaStudio A simple return is a good solution. The magnetic attachment might not be very convenient for attaching to glass, and having a large magnet inside could scratch the glass.

BI1SCY Do you mean we're using a combined setup? Haha haha. Both the 10W handheld and the Yagi antenna are reliable. Since I don't have much money, I made my own suction cup mount myself. Haha haha.

You need a directional antenna. Point it outwards. It can effectively reach potted plants on your balcony. A directional antenna doesn't require high gain. Two or three Yagi antennas are sufficient. I guarantee that the signal will not be wasted and will go out.

BI1SCY

BH2RSJ Okay, thank you for the suggestion.

BI3WKD

The worst case scenario would be to replace it with a powerful handheld radio, paired with an Eagle, which would definitely suffice.

BI1SCY

BI3WKD Thank you for the suggestion. I recently purchased a UV380 and am planning to experiment with it.

Could I try using a rubber suction cup?

BI1SCY

DARK Ideally, I also asked about this a few days ago in Changping.

First, eliminate indoor support poles; those installed outside or near windows are almost certainly better than those inside.
When considering U-shaped antennas, a three-unit CJU antenna might be the best solution for mounting on the window sill.

DARK

YofoaStudio As for the higher levels, I don't recommend it. After all, while this device seems to hold suction well, unless you remove it immediately after use, it can actually be quite dangerous. The external environment temperature also affects its performance. I have also purchased a suction cup attachment to keep in my car and take out when needed. If not in use, I simply put it back in the car. Could someone recommend a good antenna? Something for around 5-10 thousand yuan that works with a handheld device. And please, nothing too expensive! I can't afford a Diamond one.

The best option is to use it outdoors.
